Formation dynamics of exciton polariton vortices created by non-resonant annular pumping
Bernd Berger, Daniel Schmidt, Xuekai Ma +4
We study the spontaneous formation of exciton polariton vortices in an all-optical non-resonantly excited annular trap, which is formed by ring-shaped subpicosecond laser pulses. S…
Dynamics of the Optical Spin Hall Effect
Daniel Schmidt, Bernd Berger, Manfred Bayer +6
We study the time evolution of the Optical Spin Hall Effect (OSHE), which occurs when exciton-polaritons undergo resonant Rayleigh scattering. The resulting spin pattern in momentu…
Observation of three-particle complexes in WS monolayers
J. Jadczak, J. Kutrowska-Girzycka, P. Kapuscinski +6
Atomically thin semiconducting transition-metal dichalcogenides provide novel insights into the physics of many-body effects mediated by Coulomb interactions. Here, we report on te…
Temperature-dependent dielectric function of bulk SrTiO: Urbach tail, band edges, and excitonic effects
Pranjal Kumar Gogoi, Daniel Schmidt
We report the temperature-dependent complex dielectric function of pristine bulk SrTiO between 4.2 and 300 K within the energy range of 0.6-6.5 eV determined by spectroscopic e…
Effect of antimony substitution in iron pnictide compounds
D. Schmidt, H. F. Braun
In the present study we have examined the effect of negative chemical pressure in iron pnictides. We have synthesized substitution series replacing arsenic by antimony in a number…
Anisotropic optical properties of rhombohedral and tetragonal thin film BiFeO phases
Daniel Schmidt, Lu You, Xiao Chi +2
The anisotropic optical properties of multiferroic BiFeO thin films have been determined with Mueller matrix ellipsometry at room-temperature. The full dielectric tensors of te…
