This topical review addresses how semiconductor systems may reveal scalable properties
similar to those known from Rydberg atoms and in which ways they may be utilized for …

This article discusses the experimental status achieved in the assessment of the hydrogen-
like series of Wannier–Mott excitons, using the semiconductor cuprous oxide, Cu 2 O, as …

Rydberg excitons are, with their ultrastrong mutual interactions, giant optical nonlinearities,
and very high sensitivity to external fields, promising for applications in quantum sensing …

Due to quantum confinement, excitons in finite-sized crystals behave rather differently than
in bulk materials. We investigate the dependence of energies of Rydberg excitons on the …

The strong intrinsic Coulomb interactions of Frenkel excitons in crystalline carbon nitride
(CCN) greatly limits their dissociation into electrons and holes, resulting in unsatisfactory …

We investigate the influence of a static, uncorrelated distribution of charged impurities on the
spectrum of bound excitons in the copper oxide Cu 2 O. We show that the statistical …

So far, the observation of the yellow P exciton series in cuprous oxide has been limited to
principal quantum numbers up to n max= 25 at a crystal temperature of T= 1.35 K. Here, we …

We numerically investigate the odd-parity states of the green exciton series in cuprous
oxide. Taking into account the coupling to the yellow series and especially to the yellow …

We study the ultrastrong driving of Rydberg excitons in Cu 2 O by a microwave field. The
effect of the field is studied using optical absorption spectroscopy, and through the …

Reflection spectra of a heterostructure with a GaAs/AlGaAs quantum well (QW) of 30 nm
wide have been studied under additional optical excitation in an external electric field. The …
