Physics logo NEWS AND COMMENTARYEntangled Mirrors Could Reflect Quantum GravityJuly 28, 2015A proposed interferometry experiment could test quantum gravity theories by entangling two mirrors weighing as much as apples.Synopsis on: Roman SchnabelPhys. Rev. A 92, 012126 (2015)EDITORS' SUGGESTIONPhoton-correlation measurements of atomic-cloud temperature using an optical nanofiberA method to measure the temperature of a cold atomic cloud is developed by relating atoms motion to fluorescence photons emitted into an optical nanofiber, where the temperature readout from the temporal correlations of the photons agrees well with standard time-of-flight measurements.J. A. Grover, P. Solano, L. A. Orozco, and S. L. RolstonPhys. Rev. A 92, 013850 (2015)EDITORS' SUGGESTIONSpin separations in the spin Hall effect of lightThe so-called spin Hall effect of light, the transverse splitting of the left circularly polarized and right circularly polarized components of light with initially linear polarization, is investigated, and the coherent superposition of two sub-components with different shifts in each component that leads to the observed phenomena is elucidated.Jin-Li Ren et al.Phys. Rev. A 92, 013839 (2015)EDITORS' SUGGESTIONNear-field speckle-scanning-based x-ray imagingA method capable of accessing the ultra-small-angle x-ray-scattering distribution of a sample from two-dimensional raster scans is developed, which promises to have applications in various fields of material science as well as biological imaging.Sebastien Berujon and Eric ZieglerPhys. Rev. A 92, 013837 (2015)EDITORS' SUGGESTIONCompatibility of state assignments and pooling of informationA measure for the compatibility of state assignments of independent observers of the same quantum system is proposed, and the possibility of arriving at a unique state assignment by pooling of information is investigated.Todd A. Brun, Min-Hsiu Hsieh, and Christopher PerryPhys. Rev. A 92, 012107 (2015)EDITORS' SUGGESTIONSpectrum of quasistable states in a strong infrared fieldThe stability of highly excited hydrogen and helium atoms subject to an intense infrared laser field is studied, and similarities to the case of microwave driving are discussed.Changchun Zhong and F. RobicheauxPhys. Rev. A 92, 013406 (2015)
