Imaging interferometry of excitons in two-dimensional structures: Can it detect exciton coherence
Heinrich Stolz, Maria Dietl Rico Schwartz, Dirk Semkat
Using the theory of imaging with partially coherent light, we derive general expressions for different kinds of interferometric setups like double slit, shift and mirror interferen…
Interaction of Rydberg Excitons in Cuprous Oxide with Phonons and Photons: Optical Linewidth and Polariton Effect
Heinrich Stolz, Florian Schöne, Dirk Semkat
We demonstrate that the optical linewidth of Rydberg excitons in Cu2O can be completely explained by scattering with acoustical and optical phonons, whereby the dominant contributi…
Rydberg excitons in the presence of an ultralow-density electron-hole plasma
J. Heckötter, M. Freitag, D. Fröhlich +7
We use two-color pump-probe spectroscopy to study Rydberg excitons in CuO in the presence of free carriers injected by above-band-gap excitation. Already at plasma densities $ρ…
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.…
