Nonlinear Rydberg exciton-polaritons in CuO microcavities
Maxim Makhonin, Anthonin Delphan, Kok Wee Song +13
Rydberg excitons (analogues of Rydberg atoms in condensed matter systems) are highly excited bound electron-hole states with large Bohr radii. The interaction between them as well…
Scrutinizing the Debye plasma model: Rydberg excitons unravel the properties of low-density plasmas in semiconductors
Heinrich Stolz, Dirk Semkat, Rico Schwartz +5
For low-density plasmas, the classical limit described by the Debye-Hückel theory is still considered as an appropriate description even though a clear experimental proof of this p…
Coherent transfer matrix analysis of the transmission spectra of Rydberg excitons in Cuprous Oxide
Heinrich Stolz, Rico Schwartz, Julian Heckötter +4
In this study we analyze the transmission spectrum of a thin plate of Cuprous Oxide in the range of the absorption of the yellow exciton states with the coherent transfer matrix me…
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…
Scaling laws of Rydberg excitons
J. Heckötter, M. Freitag, D. Fröhlich +4
Rydberg atoms have attracted considerable interest due to their huge interaction among each other and with external fields. They demonstrate characteristic scaling laws in dependen…
High resolution study of the yellow excitons in CuO subject to an electric field
J. Heckötter, M. Freitag, D. Fröhlich +4
We have used high resolution transmission spectroscopy to study the exciton level spectrum in CuO subject to a longitudinal external electric field, i.e., in the geometry where…
Magnetoexcitons in cuprous oxide
Frank Schweiner, Jörg Main, Günter Wunner +6
Two of the most striking experimental findings when investigating exciton spectra in cuprous oxide using high-resolution spectroscopy are the observability and the fine structure s…
Signatures of Quantum Coherence in Rydberg Excitons
P. Grünwald, M. Aßmann, J. Heckötter +4
Coherent optical control of individual particles has been demonstrated both for atoms and semiconductor quantum dots. Here we demonstrate the emergence of quantum coherent effects…
Observation of high angular momentum excitons in cuprous oxide
J. Thewes, J. Heckötter, T. Kazimierczuk +5
The recent observation of dipole-allowed -excitons up to principal quantum numbers of in cuprous oxide has given insight into exciton states with unprecedented spectral r…
