We study dipole interseries transitions between the yellow and green exciton series in cuprous oxide including the complex valence band structure. To this end, we extend previous studies of the spectrum of complex green exciton resonances [Phys. Rev.

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 method. We demonstrate that, in contrast to the usual analysis using Bee

We investigate the influence of a static, uncorrelated distribution of charged impurities on the spectrum of bound excitons in the copper oxide Cu$_{\text{2}}$O. We show that the statistical distribution of Stark shifts and ionisation rates leads to

Orbital angular momentum (OAM) light possesses in addition to its usual helicity ($s=\ifmmode\pm\else\textpm\fi{}\ensuremath{\hbar}$, depending on its circular polarization) an orbital angular momentum $l$. This means that in principle one can transf

We investigate the infrared optical transitions between excitons of the yellow, green, and blue series in the cuprous oxide ${\mathrm{Cu}}_{2}\mathrm{O}$. We show that, in many cases, the dipole approximation is inadequate and, in particular, that it

We investigate the formation of waveguides for Rydberg excitons in ${\mathrm{Cu}}_{\text{2}}\mathrm{O}$ from cylindrical stressors as alternatives to optical traps. We show that the achievable potential depths can easily reach the meV and the trap fr

Recent high-resolution absorption spectroscopy on excited excitons in cuprous oxide [Nature (London) 514, 343 (2014)] has revealed significant deviations of their spectrum from that of the ideal hydrogen-like series. Here we show that the complex ban
