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 …

The oxides of copper have attracted the attention of scientists already for more than hundred
years. This fascination is fueled by many outstanding properties of the material, for example …

Giant Rydberg excitons with principal quantum numbers as high as n= 25 have been
observed in cuprous oxide (Cu2O), a semiconductor in which the exciton diameter can …

The realization of exciton polaritons—hybrid excitations of semiconductor quantum well
excitons and cavity photons—has been of great technological and scientific significance. In …

Symmetries are the underlying principles of fundamental interactions in nature. Chaos in a
quantum system may emerge from breaking these symmetries. Compared to vacuum …

We investigate the neutralization of charged defects in a Cu 2 O crystal experimentally with a
continuous-wave two-color pump-probe setup. We demonstrate that the excitation of high …

Recent high-resolution absorption spectroscopy on excited excitons in cuprous oxide
[Nature (London) 514, 343 (2014) NATUAS 0028-0836 10.1038/nature13832] has revealed …

Rydberg atoms have attracted considerable interest due to their huge interaction among
each other and with external fields. They demonstrate characteristic scaling laws in …

We investigate the nonlinear refraction induced by Rydberg excitons in Cu 2 O. Using a high-
precision interferometry imaging technique that spatially resolves the nonlinear phase shift …

Most photovoltaic absorbers are identified using the standard Shockley-Queisser selection
principle which relies on optimal band-gap values. However, this criterion has been shown …
