17 - 22 July 2016

Santa Fe Community Convention Center, Santa Fe, New Mexico, USA

Welcome to Santa Fe and to the International Conference on Ultrafast Phenomena! This year’s event – the 20th biannual international conference – continues the tradition of bringing together a multidisciplinary group of researchers and students sharing a common interest in science and technology at the frontiers of ultrafast technology. Scientists and engineers from all over the world will converge in beautiful Santa Fe to take part in this event. The conference will include oral and poster contributions. We have scheduled 12 invited, 135 oral and 143 poster presentations over what should be four and half full days. The presentations are in our opinion exceptional in their scientific quality and range of topics. A sponsor exhibit featuring leading companies will be held in conjunction with the meeting. We hope that you will enjoy the unique beauty of Santa Fe, the program, and the opportunity to spend time with colleagues from around the globe.

EXPLANATION OF SESSION CODES

Meeting Name Number U = Ultrafast Phenomena Presentation order within the Session

Day of the Week Series Number Session Designation M = Monday 1 = First Series of Sessions Alphabetically Tu = Tuesday 2 = Second Series of Sessions W = Wednesday 3 = Third Series of Sessions Th = Thursday 4 = Forth Series of Sessions The first letter of the code designates the meeting. The second element denotes the day of the week (M = Monday, Tu = Tuesday, W = Wednesday, Th = Thursday, F = Friday). The third element indicates the session series in that day (for instance, 1 would denote the first sessions in that day). Each day begins with the letter A in the fourth element and continues alphabetically through the parallel session. The lettering then restarts with each new series. The number on the end of the code (separated from the session code with a period) signals the position of the talk within the session (first, second, third, etc.). For example, a presentation coded UM2A.4 indicates that this paper is being presented on Monday (M) in the second series of sessions (2) and is the first parallel session (A) in that series and the fourth paper (4) presented in that session.

Scholes1; 1Chemistry, Princeton Univ., USA; 2Physics, Univ. of Connecticut, USA; 3NHFML, Florida State Univ., USA. Ultrafast coherences in photosynthetic algae proteins are discriminated by using 25T-magnetic field coupled with a pump-probe apparatus. Electronic/vibronic coherences are modulated by the presence of the field, while vibrations are not perturbed.

UM3A.4 • 15:00 New Insight into Photophysics of DNA Nucleobases, Valentyn Prokhorenko1, Alessandra Picchiotti1, R. J. Dwayne Miller1; 1Max Planck Inst., Germany. Using broadband deep-UV transient absorption and electronic 2D spectroscopies we found that in all DNA nucleobases the photodeactivation of excited-state population occurs in two steps via a “dark” state which presumably is a nπ* state.

UM3A.5 • 15:15 Cavity-Enhanced Ultrafast Spectroscopy: Ultrafast meets Ultrasensitive, Thomas K. Allison1, Melanie A. Reber1, Yuning Chen1; 1SUNY Stony Brook, USA.

Quantum chemical models are employed to investigate the photoisomerization dynamics of distant rhodopsins. It is found that animal rhodopsins avoid a region of electronic degeneracy present in microbial rhodopsins thus achieve a much faster isomerization.

Scholes1; 1Princeton Univ., USA; 2Chemistry, Univ. of Toronto, Canada. Two-dimensional electronic spectroscopy and broadband transient absorption were executed over the full spectrum of phycocyanin 645 (PC645, Chroomonas mesostigmatica) at 295 and 77 K to reveal vibronic coherence between donor/acceptors separated by >1500 cm-1.

Presider: James Cryan; SLAC National Accelerator Lab, USA

UTu1A.1 • 08:30 Toward Femtochemistry with Circular Polarized Pulses., Samuel Beaulieu1, Antoine Comby1, Romain Geneaux2, Dominique Descamps1, Baptiste Fabre1, Amelie Ferre5, Gustavo Garcia3, François Légaré4, Yann Mairesse1, Laurent Nahon3, Stéphane Petit1, Bernard Pons1, Thierry Ruchon2, Valérie Blanchet1; 1Université de Bordeaux I, France; 2CEA, IRAMIS, Lasers, Interactions and Dynamics Lab, France; 3Synchrotron SOLEIL, France; 4Centre ÉMT, Institut National de la Recherche Scientifique, Canada; 5CNRS, LP3, France. Femtochemistry induced by circularly polarization light coupled to velocity map imaging of photoelectron gives an access to new and sensitive observables that have to be compared to the standard ones.

UTu1A.2 • 09:00 Electronic Dynamics in Highly Excited States of Acetone and Methyl Azide Studied with Ultrafast PEPICO Spectroscopy, William Peters1, David E. Couch1, Ryan C. Fortenberry2, Henry C. Kapteyn1, Margaret M. Murnane1; 1Physics, Univ. of Colorado, USA; 2Chemistry, Georgia Southern Univ., USA. Excited electronic states near 8.0 eV are studied using femtosecond PEPICO spectroscopy, accessing dense manifolds of strongly coupled states. Ionization to multiple cation states is crucial for navigating the mixed states of this energy regime.

UTu1A.3 • 09:15 New Insights into Ultrafast Relaxation Dynamics of the Ethylene Cation C2H4

+, Matteo Lucchini1, André Ludwig1, Elisa Liberatore2, Jens Herrmann1, Lamia Kasmi1, Lukas Gallmann1,3, Ursula Roethlisberger2, Ursula Keller1; 1Dept. of Physics, ETH Zurich, Switzerland; 2Lab of Computational Chemistry and Biochemistry, EPFL, Switzerland; 3Inst. of Applied Physics, Univ. of Bern, Switzerland. Ultrafast relaxation dynamics of the ethylene cation are investigated with unprecedented temporal resolution. This enabled us to redefine the isomerization time to 30 fs and identify relaxation channels evolving on time scales <50 fs.

UTu1A.4 • 09:30 Evidence of Hydrogen Migration rather than Isomerization in the Acetylene Dication, Chelsea E. Liekhus-Schmaltz1,2, Zheng Li1,2, Vladimir Petrovic1,2, Todd Martinez1,2, Philip H. Bucksbaum1,2; 1Stanford Univ., USA; 2PULSE Inst., USA. New ab initio calculations show that ultrafast isomerization in the acetylene dication has an extremely low probability because dissociation outcompetes isomerization. We propose that isomerization previously described in recent ultrafast LCLS x-ray experiments are in fact due to partial migration.

UTu1A.5 • 09:45 Attosecond Pump-Probe Spectroscopy of Electron Correlation Dynamics in the Double Ionization of Benzene, Alexander Winney1, Suk Kyoung Lee1, Yunfei Lin1, Qing Liao1, Pradip Adhikari1, H.

Bucksbaum1,2; 1SLAC National Accelerator Lab, USA; 2Physics, Stanford Univ., USA. We observe a sharp peak in angle-resolved H2

Anisotropy of strain field in epitaxial film significantly affects the transition rate.

UTu4A.49 • Effects of Film-Substrate Interaction on Ultrafast Dynamics in the Photo-Induced Phase Transition in Vanadium Dioxide, Richard F. Haglund1, Nathan Brady2, David Hilton2, Minah Seo3, Joyeeta Nag1, Rohit Prasankumar3, Kannatassen Appavoo1, Felipe Rivera4, Robert Davis4, Richard Vanfleet4; 1Vanderbilt Univ., USA; 2Univ. of Alabama-Birmingham, USA; 3Los Alamos National Lab, USA; 4Brigham Young Univ., USA. Ultrafast pump-priobe spectroscopy shows that the photo-induced monoclinic-to-rutile phase transformation in vanadium dioxide thin films occurs in 40±0.5 ps independent of nanograin morphology, because substrate-inducced strain leads to common families of grain orientations.

We use ultrafast vibronic spectroscopy to study how in organic semiconductors vibrational modes couple to electronic excitations to drive the conversion of singlet excitons to entangled triplet pair states via the process of singlet fission.

UW3A.2 • 14:30 Ultrafast Spatial Dynamics of Excitons During Intramolecular Singlet Fission, Matthew Sfeir1, Samuel Sanders2, Elango Kumarasamy2, Andrew Pun2, Kannatassen Appavoo1, Michael Steigerwald2, Luis Campos2; 1Center for Functional Nanomaterials, Brookhaven National Lab, USA; 2Chemistry, Columbia Univ., USA. Using ultrafast transient absorption and emission spectroscopy, we probe the spatial dynamics of excitons during intramolecular singlet fission in asymmetric oligoacene heterodimers. Exciton-exciton correlations are crucial for promoting both triplet pair formation and recombination.

UW3A.3 • 14:45 Singlet Fission Mediating States in TIPS-Pentacene and its Aza-Derivatives Uncovered by Pump-Depletion-Probe Spectroscopy, Tiago Buckup1, Julia Herz1, Fabian Paulus2, Jens Engelhart2, Uwe Bunz2, Marcus Motzkus1; 1Physikalisch-Chemisches Institut, Ruprecht-Karls-Universität Heidelberg, Germany; 2Organisch-Chemisches Institut, Ruprecht-Karls-Universität Heidelberg, Germany. Femtosecond pump-depletion-probe experiments were carried out in order to unveil the ultrafast excited singlet fission dynamics of TIPS-pentacene derivatives. The extremely short-lived intermediate 1TT state is revealed and the nitrogen-substitution leads to shorter dynamics.

UW3A.4 • 15:00 Long-Lived Vibronic Coherence in Pentafluorobenzene in the ππ* Excited State, Ole Hüter1, Matthieu Sala1, Dassia Egorova1, Friedrich Temps1; 1Christian-Albrechts-Univ. Kiel, Germany.

Two-dimensional electronic spectroscopy with sub-10-fs time resolution shows that coherent vibronic coupling promotes charge delocalization and results in long-lasting coherent oscillatory dynamics of strongly coupled excitons and polaron-pairs in a conjugated polymer thin film at room temperature.

UW3A.6 • 15:30 Observation of an Excitonic Quantum Coherence in CdSe Nanocrystals, Shuo Dong1, Dhara Trivedi2, Sabyasachi Chakrabortty3, Takayoshi Kobayashi4, Yinthai Chan3, Oleg Prezhdo5, Zhi-Heng Loh1; 1Nanyang Technological Univ. , Singapore; 2Univ. of Rochester, USA; 3National Univ. of Singapore, Singapore; 4Univ. of Electro-Communications, Japan; 5Univ. of Southern California, USA. Optical pump-probe spectroscopy with 6-fs pulses elucidates the 1Se1S3/2–1Se2S3/2 excitonic quantum coherence in CdSe nanocrystals. This coherence encodes hole migration over nanometer length scales and markedly alters the displacement amplitudes of coherent phonons.

We report a new technique to amplify coherent acoustic phonons in a semiconductor superlattice under intraminiband transport. The interaction between drift electrons and copropagating acoustic phonons leads to an amplification of the sound amplitude by 200%. UW4A.2 • Ultrafast plasmonic dephasing dynamics studied by time-resolved spectroscopy based on SHG-FROG methods, Atsushi Sugita1, Sunsuke Nihashi1, Atsushi Ono1, Yoshimasa Kawata1; 1Shizuoka Univ., Japan. Ultrafast optical response of localized surface plasmons in Au nanorods are presented. The dynamics of the plasmonic polarizations was examined with the time-resolved spectroscopy based on SHG-FROG and the dephasing time ~15 fs was estimated. UW4A.3 • Manipulating Ultrafast Nondiabatic Dynamics of Molecules in Optical Cavities, Markus Kowalewski1, Kochise Bennett1, Shaul Mukamel1; 1Chemistry, Univ. of California, Irvine, USA. Strong coupling of molecules to the vacuum field of a cavity can modify the potential energy surfaces, opening new photochemical reaction pathways. We theoretically investigate the ultrafast dynamics of molecules confined in optical micro cavities. UW4A.4 • Ultrashort Strain Pulses Generated at Buried GaP/Si Interfaces, Kunie Ishioka1, Avinash Rustagi2, Andreas Beyer3, Kerstin Volz3, Wolfgang Stolz3, Ulrich Hoefer3, Hrvoje Petek4, Christopher Stanton2; 1National Inst. for Materials Science, Japan; 2Univ. of Florida, USA; 3Marburg Univ., Germany; 4Univ. of Pittsburgh, USA. Photoexcitation of a GaP/Si(001) interface generates an ultrafast acoustic pulse with temporal width <1 ps which propagates ballistically in the GaP layer and is detected as an echo in reflectivity when it reaches GaP/air surface. UW4A.5 • Time-domain study for Fano resonance in p-type Si, Keiko Kato1, Yuya Hasegawa1,2, Katsuya Oguri1, Tadashi Nishikawa2, Hideki Gotoh1; 1NTT Basic Research Labs, Japan; 2Tokyo Denki Univ., Japan. Sub-10-fs laser pulses allow time-resolved observation of discrete and continuum states under Fano resonance in p-type Si. The temperature dependence of the Fano parameter mainly originates from an initial phase shift of the phonons. UW4A.6 • Ultrafast Multiexciton Dynamics and Optical Gain Development in Perovskite Semiconductor Nanocrystals, Chunfeng Zhang1, Yanqing Xu1, Qi Chen1, Bin Li1, Min Xiao2; 1Nanjing Univ., China; 2Physics, Univesity of Arkansas, USA. We perform ultrafast transient absorption spectroscopy to study the exciton dynamics relevant to optical gain in perovskite CsPbBr3 nanocrystals.

UW4A.7 • Influence of rotational wavepackets on the nitrogen ion emission in filaments, Ladan Arissian1, Brian Kamer1, Chengyong Feng1, Amin Rasoulof1, Jean-Claude M. Diels1; 1Univ. of New Mexico, USA. We study the effect of rotational states of nitrogen ion on the emission at 428nm. A comparison between different pump wavelengths and polarizations suggest crucial dependence of stimulated emission on the stimulated rotational Raman scattering.

Complex near-infrared refractive-index spectra of Si and GaAs wafers were characterized by dual-comb spectroscopy (DCS). Transient interferogram was observed for an InGaAs-based saturable absorber in time-resolved DCS, demonstrating potential as a full-characterization tool. UW4A.10 • No Substantial Asymmetries in the Ion Emission from Metal Cluster Nanoplasmas, Dzmitry Komar1, Robert Irsig1, Josef Tiggesbaeumker1, Karl-Heinz Meiwes-Broer1; 1Univ. Rostock, Germany. The charge-state resolved energy spectra of 30fs laser-excited Ag clusters show an almost isotropic emission. Our findings contradict recent findings on rare gas clusters that ions are emitted perpendicular to the polarization axis.

UW4A.11 • High-Field THz Lattice Control Via Anharmonic Vibrational Coupling, Jeremy A. Johnson1, Parker D. Salmans1, Nicholas R. Ellsworth1; 1Brigham Young Univ., USA. Using high-field THz radiation, we drive IR active vibrations in CdWO4 to large amplitudes. This large amplitude excitation allows anharmonic coupling, which leads to coherent energy transfer, exciting a set of Raman active modes. UW4A.12 • Transient Transparency of Water Induced by High-Field Terahertz Pulses, Jeffrey A. Davis1, Fabio Novelli1; 1Swinburne Univ. of Technology, Australia. The non-linear response of water to strong THz fields leads to enhanced transmission and corresponds to a decrease of the static dielectric constant by an amount almost three orders of magnitude larger than for DC fields. UW4A.13 • Gas-based time-resolved THz time-domain spectroscopy for the study of nonequilibrium electron-phonon interaction in semiconductors, Lucas K. Huber1, Filippos Kapsalidis1, Steven L. Johnson1; 1ETH Zurich, Switzerland. Using a fully gas-based wideband THz spectrometer we show evidence of strongly nonequilibrium electron-phonon dynamics in InSb.

Nelson1; 1Dept. of Chemistry, MIT, USA; 2Inst. of Physics, Academy of Sciences of the Czech Republic, Czech Republic. Using the terahertz (THz) Kerr effect, we record nonlinear time-domain vibrational responses in tris-sarcosine calcium chloride (TSCC) through two-photon processes with THz fields. The results reveal two Raman-active modes at 1.0 and 1.24 THz excited by THz fields. UW4A.15 • Ultrafast Light Scattering by Transient Inhomogeneities in Vanadium Dioxide, Sergiy Lysenko1, Armando Rua1, José Figueroa1, Lee Chevres1, Félix Fernández1; 1Dept. of Physics, Univ. of Puerto Rico, USA. The VO2 morphology and structural defects both affect the light-induced insulator-to-metal phase transition dynamics on the mesoscale. Angle-resolved light scattering reveals substantial differences in transient statistics of optical inhomogeneities for non-epitaxial and crystalline epitaxial films. UW4A.16 • Femotosecond Carrier Dynamics of Metallic Single-Walled Carbon Nanotubes under Applied Bias-Voltage, Ikufumi Katayama1, Keisuke Maekawa1, Yasuo Minami1, Masahiro Kitajima1,2, Kazuhiro Yanagi3, Jun Takeda1; 1Yokohama National Univ., Japan; 2LxRay Co. Ltd., Japan; 3Tokyo Metropolitan Univ., Japan. We have investigated bias-voltage dependence of carrier dynamics in metallic single-walled carbon nanotubes. By tuning the Fermi energy with the bias-voltage, the carrier relaxation time becomes minimum near the Dirac point, indicating the carrier-carrier interaction. UW4A.17 • Ultrafast Relaxation of Multi-electronic States in Benzene Cations Induced by XUV Pulses, Martin C. Galbraith1, Nickolai Zhavoronkov1, Christopher T. Smeenk1, Alexandre Marciniak2, Victor Despré2, Jochen Mikosch1, Marc Vrakking1, Oleg Kornilov1, Franck Lépine2; 1Max Born Inst., Germany; 2Institut Lumiere Matiere, France. We investigate the relaxation dynamics of multi-electronic states in benzene cations produced by ultrashort (<7 fs) XUV pulses.

UTh4A.38 Verification of Nonadiabatic Orientation of CO Molecules with a FemtosecondTtwo-Color Laser Pulse Studied by High-Order Harmonic Generation and Coulomb Explosion Imaging, Shinichirou Minemoto1, Wataru Komatsubara2, Hirofumi Sakai1; 1Graduate School of Science, The Univ. of Tokyo, Japan; 2School of Science, The Univ. of Tokyo, Japan. The actual degree of orientation <cos\theta> of CO molecules pumped by a femtosecond two-color pulse is found to be much lower than the value estimated by the intensity ratio between the even- and odd-order harmonics.

UTh4A.39 • Probing Ionization Dynamics with Attosecond Transient Absorption Spectroscopy, Henry Timmers1, Mazyar Sabbar1, Yi-Jen Chen2,3, Robin Santra2,3, Daniel M. Neumark1,4, Stephen R. Leone1,4; 1Univ. of California, Berkeley, USA; 2Physics, Univ. of Hamburg, Germany; 3Center for Free-Electron Laser Science, Germany; 4Lawrence Berkeley National Lab, USA. Attosecond transient absorption experiments are performed to study strong-field ionization dynamics in xenon and methyl bromide. Results in Xe depict half-cycle ionization steps that exhibit an apparent time delay between spin-orbit ionization channels. UTh4A.40 NIR ionization avalanching in clusters ignited by ultrashort XUV pulses, Bernd Schuette1,2, Mathias Arbeiter3, Alexandre Mermillod-Blondin1, Marc Vrakking1, Arnaud Rouzée1, Thomas Fennel3; 1Max-Born-Institut, Germany; 2Dept. of Physics, Imperial

College London, UK; 3Univ. of Rostock, Germany. We present a novel method to spatially and temporally control avalanching in clusters. An XUV pulse generates seed electrons, which are efficiently heated by an NIR laser pulse, leading to extensive ionization at moderate intensities.

UTh4A.41 High-Power Narrow-Linewidth Yb:fiber Laser Frequency Comb, Xinlong Li1, Peng Zhao1, Christopher Corder2, Thomas K. Allison1; 1Stony Brook Univ., SUNY, USA; 2Stony Brook Univ., USA. Cavity enhanced high harmonic generation can provide XUV pulses with high repetition rate. In this summary, we present a Yb:fiber laser with 55 W average output power, 150 fs pulse duration and 78 MHz repetition rate ideal for driving cavity-enhanced HHG.

UTh4A.42 Toward Octave-Spanning Coherent Near-field Control in Plasmonic Nanostructures, Michael Mrejen1, Uri Arieli1, Assaf Levanon1, Achiya Nagler1, Haim Suchowski1; 1Physics Dept., Tel Aviv Univ., Israel. We experimentally observe hyperspectral near-field response of a single plasmonic nanostructure, using a combined nano-FTIR SNOM illuminated by ultra-broadband few-cycle femtosecond source. Control of the spectral response across the nanpoostructure is achieved.

UTh4A.43 Coherent Diffractive Imaging of Laser-Driven Plasma Dynamics in Thin Foils, Neeke Rothe1, Christoph Merschjann2, Hannes Bassen1, Franziska Fennel1, Thomas Fennel1, Stefan Lochbrunner1; 1Univ. Rostock, Germany; 2Free Univ. Berlin, Germany. A microplasma generated by a fs-800 nm pulse focused onto a 30 nm gold foil is probed via coherent diffractive imaging at 400 nm. The solid matter response is reconstructed from the holograms which reflect space and time dependent complex transmittance.

UTh4A.44 Optically induced nanoscale networks of topological magnetic defects, Tim Eggebrecht2, Marcel Möller1, Jan-Gregor Gatzmann1, Nara Rubiano da Silva1, Armin Feist1, Ulrike Martens3, Henning Ulrichs2, Markus Münzenberg3, Claus Ropers1, Sascha Schäfer1; 14th Physical Inst.- Solids and Nanostructures, Georg-August-Univ., Germany; 21st Physical Inst., Georg-August-Univ., Germany; 3Interface and Surface Physics, Univ. of Greifswald, Germany. Lorentz microscopy with in-situ femtosecond laser excitation allows for the investigation of optically triggered magnetic processes with nanometer spatial resolution. Here, we demonstrate the light-induced formation of nanoscale magnetic vortex-antivortex networks in thin iron layers.

UTh4A.45 • Establishing Distinct Charge Transfer Channels in Indoline Dye Sensitized Electrodeposited ZnO Solar Cells, Iulia Minda1, Essraa Ahmed1, Vivien Sleziona1, Christoph Richter2, Max Beu2, Jane Falgenhauer2, Hidetoshi Miura3, Derck Schlettwein2, Heinrich Schwoerer1; 1Univ. of Stellenbosch, South Africa; 2Justus-Liebig Univ., Germany; 3Chemicrea Co. Ltd., Japan. We directly observe three electron injection channels from photoexcited indoline dye to

electrodeposited ZnO by femtosecond transient absorption spectroscopy in the visible and infrared spectral regions and identify two distinct transient surface intermediate states. UTh4A.46 Watching Molecular Excitons Move, Maxim S. Pshenichnikov2,1, Oleg V. Kozlov2,1, Foppe de Haan2,1, Ross A. Kerner3,4, Barry P. Rand3,4, David Cheyns5; 1Rijksuniversiteit Groningen, Netherlands; 2Zernike Inst. for Advanced Materials, Netherlands; 3Dept. of Electrical Engineering and Andlinger Center for Energy and the Environment, USA; 4Princeton Univ., USA; 5IMEC, Belgium. A novel spectroscopic method to track dynamics of the molecular excitons in organic semiconductors with femtosecond accuracy is proposed and realized. Extremely efficient exciton diffusion in vacuum-deposited C70 fullerene layers is demonstrated.

UTh4A.47 Investigating the breakdown of the continuum model in ultrafast vibrations of small metal nanoparticles and clusters, Tatjana Stoll1,2, Vincent Juvé2, Paolo Maioli2, Aurélien Crut2, Giulio Cerullo1, Fabrice Vallee2, Natalia Del Fatti2; 1Politecnico di Milano, Italy; 2Institut Lumière Matière, France. Ultrafast mechanical vibrations of small metal nanoparticles and atomically defined clusters are investigated by femtosecond transient absorption spectroscopy. The transition from continuous elasticity to molecular dynamics is explored by analyzing the size dependence of vibrational frequencies.

UTh4A.48 Laser-Assisted Elastic Electron Scattering by Light-Dressed Xe Atoms in a Femtosecond Intense Laser Field, Reika Kanya1, Yuya Morimoto1, Kaoru Yamanouchi1; 1Dept. of Chemistry, School of Science, The Univ. of Tokyo, Japan. The light-dressing effect in laser-assisted elastic electron scattering of Xe was investigated, and its application to probing ultrafast evolution of electron distributions in atoms and molecules in intense laser fields was discussed.

UTh4A.49 • Thickness Dependent Electron-Lattice Equilibration in Thin Bi-Films Studied by Time-Resolved MeV Electron Diffraction, Klaus Sokolowski-Tinten1; 1Universität Duisburg-Essen, Germany. Using time-resolved electron diffraction the electron-lattice equilibration in laser-excited thin Bi-films has been investigated. Our data reveal a pronounced thickness-dependence which is attributed to cross-interfacial coupling of hot electrons in the Bi-film to substrate phonons. UTh4A.50 • Ultrashort pulse assisted electron emission from carbon cathodes, Jennifer A. Elle1, Daniel Enderich2, Adrian Lucero3, Wilkin Tang1, Andreas Schmitt-Sody1, Timothy Knowles4, Don Shiffler1; 1AFRL, USA; 2Univ. of Wisconsin , USA; 3Boeing DES, USA; 4Energy Science Labs Inc, USA. Electron emission with an ultrashort laser for single and double tipped carbon fiber field emitters is studied. Single-tip experiments demonstrate emission changes from multiphoton to single-photon assisted tunneling. Double-tip measurements do not evidence screening effects.

We report the observation of nonperturbative high-harmonic generation from monolayer MoS2. The yield is higher in monolayer compared to a single layer of the bulk, an effect attributed to strong electron-hole interactions in the monolayer.

UF2A.3 • 11:30 Isotope Effect in the three Break-up Channels of the Acetylene Cation, Heide Ibrahim1, Benji Wales3, Samuel Beaulieu1, Bruno E. Schmidt2,1, Nicolas Thire1, Eric Bisson1, Vincent Wanie1, Jean-Claude Kieffer1, Michael Schuurman4, Joseph Sanderson3, François Légaré1; 1INRS EMT, Canada; 2few-cycle Inc., Canada; 3Dept. of Physics and Astronomy, Univ. of Waterloo, Canada; 4National Research Council of Canada, Canada.

We experimentally demonstrate the generation of sub-10-fs population inversion in N2

+ induced by few-cycle intense laser pulses, and theoretically clarify that the ultrafast population inversion results from the post-ionization dynamics through multiple states coupling.

UF2A.6 • 12:15 Direct observation of efficient heat dissipation in close-packed nanoheaters using coherent EUV beams, Jorge Nicolas Hernandez Charpak1, Travis Frazer1, Joshua Knobloch1, Weilun Chao2, Damiano Nardi1, Kathleen Hoogeboom-Pot1, Henry C. Kapteyn1, Margaret M. Murnane1; 1JILA-CU Boulder, USA; 2LBNL, USA. We use coherent EUV beams to probe transport away from nanoheater arrays of varying width, spacing and substrate. We validate new collectively-diffusive transport predictions, where nanowires cool faster when closely spaced than when widely separated.
