Magnetoexcitons break antiunitary symmetries
Frank Schweiner, Jörg Main, Günter Wunner
We show analytically and numerically that the application of an external magnetic field to highly excited Rydberg excitons breaks all antiunitary symmetries in the system. Only by…
Bose-Einstein condensates with balanced gain and loss beyond mean-field theory
Dennis Dast, Daniel Haag, Holger Cartarius +2
Most of the work done in the field of Bose-Einstein condensates with balanced gain and loss has been performed in the mean-field approximation using the PT-symmetric Gross-Pitaevsk…
Impact of the valence band structure of CuO on excitonic spectra
Frank Schweiner, Jörg Main, Matthias Feldmaier +2
We present a method to calculate the exciton spectra of all direct semiconductors with a complex valence band structure. The Schrödinger equation is solved using a complete basis s…
Dynamics of Solitons in the One-Dimensional Nonlinear Schrödinger Equation
Tobias Ilg, Ramona Tschüter, Andrej Junginger +2
We investigate bright solitons in the one-dimensional Schrödinger equation in the framework of an extended variational approach. We apply the latter to the stationary ground state…
Bifurcations and exceptional points in a PT-symmetric dipolar Bose-Einstein condensate
Robin Gutöhrlein, Holger Cartarius, Jörg Main +1
We investigate the bifurcation structure of stationary states in a dipolar Bose-Einstein condensate located in an external PT-symmetric potential. The imaginary part of this extern…
Linewidths in excitonic absorption spectra of cuprous oxide
Frank Schweiner, Jörg Main, Günter Wunner
We present a theoretical calculation of the absorption spectrum of cuprous oxide based on the general theory developed by Y. Toyozawa. An inclusion…
