Exceptional points in anisotropic planar microcavities
Steffen Richter, Tom Michalsky, Chris Sturm +3
Planar microcavities allow the control and manipulation of spin-polarization, manifested in phenomena like the optical spin Hall effect due to the intrinsic polarization mode split…
Antiferromagnetic phase transition in the temperature-dependent NIR-VUV dielectric function of hexagonal YMnO
Steffen Richter, Stefan G. Ebbinghaus, Marius Grundmann +1
Hexagonal YMnO is well known for the co-occurrence of ferroelectricity and antiferromagnetism at low temperatures. Using temperature-dependent spectroscopic ellipsometry at an…
Discrete relaxation of exciton-polaritons in an inhomogeneous potential
T. Michalsky, H. Franke, C. Sturm +2
We present indications, that the wave function-stiffness condition during energy-relaxation as observed in single-phase state quantum systems manifests also in a single particle en…
Room-temperature condensation in whispering gallery microresonators assisted by longitudinal optical phonons
Christof P. Dietrich, Rüdiger Schmidt-Grund, Tom Michalsky +2
We report condensation of hexagonal whispering gallery modes (WGM) at room temperature in ZnO microwires that embody nearly perfect polygonal whispering gallery microresonators. Th…
Phonon-Assisted Lasing in ZnO Microwires at Room Temperature
T. Michalsky, M. Wille, C. P. Dietrich +4
We report on room temperature phonon-assisted whispering gallery mode (WGM) lasing in ZnO microwires. For WGM laser action on the basis of the low gain phonon scattering process hi…
Electronic excitations and structure of Li2IrO3 thin films grown on ZrO:Y (001) substrates
Marcus Jenderka, Rüdiger Schmidt-Grund, Marius Grundmann +1
Thin films are a prerequisite for application of the emergent exotic ground states in iridates that result from the interplay of strong spin-orbit coupling and electronic correlati…
