Multicomponent exciton gas in cuprous oxide: cooling behaviour and the role of Auger decay
Dirk Semkat, Siegfried Sobkowiak, Florian Schöne +3
In this paper we present a hydrodynamic model to describe the dynamics of para- and orthoexcitons in cuprous oxide at ultralow temperatures inside a stress induced potential trap.…
Condensation of Excitons in Cu2O at Ultracold Temperatures: Experiment and Theory
Heinrich Stolz, Rico Schwartz, Frank Kieseling +7
We present experiments on the luminescence of excitons confined in a potential trap at milli-Kelvin bath temperatures under cw-excitation. They reveal several distinct features lik…
Phase separation of multicomponent excitonic Bose-Einstein condensates
Siegfried Sobkowiak, Dirk Semkat, Heinrich Stolz +2
For the observation of Bose-Einstein condensation, excitons in cuprous oxide are regarded as promising candidates due to their large binding energy and long lifetime. High particle…
Interacting multi-component exciton gases in a potential trap: phase separation and Bose-Einstein condensation
S. Sobkowiak, D. Semkat, H. Stolz +2
The system under consideration is a multi-component gas of interacting para- and orthoexcitons confined in a three dimensional potential trap. We calculate the spatially resolved o…
