P.R.I.M.E. project: Semiconductor nanoplasmonics
Bringing together the best of two world: nanoscaled
semiconductors and plasmonic structures
Nanostructured metal gives ultimate control over light field:
localisation and enhancement of light field
Light-matter interaction with semiconductor nanostructures
Modified transitions can be excited
Very beneficial due to high controllability

Research field: Theoretical semiconductor physics
Size of a few nanometers (1 nm=0.000 000 001 m)
Fabricated of semiconducting materials: tailored structures
Properties similar to atoms, but consist of about 104 atoms
Applications: Optoelectronics, lasers, LEDs, quantum
information, quantum cryptography, solar cells, ...
Optical control of quantum dots, state preparation,
dephasing of excitonic states
Phonon dynamics, squeezed phonons, generation of
phonon wave packets
Coherent spin dynamics, switching of spin states, time-
resolved optical signals
Twisted light-matter interaction
Example: Quantum dot doped with a single Manganese (Mn) atom
Mz= - 5/2
Mz= - 1/2
Mz=+3/2
Mn has six spin states
“quantum dice”
Switching into each spin states by
optical excitation
Visible in time-resolved spectra by
shift of the absorption line
Research interests: Ultrafast dynamics in quantum dots
Semiconductors are widely used in computers,
smartphones...
Theoretical modelling of dynamical processes in
semiconductors
Nanostructuring allows for new, fascinating effects
Specific nanostructure: quantum dots
