Rydberg excitons in CuO at millikelvin temperatures
Julian Heckötter, David Janas, Marc Aßmann +1
Rydberg excitons in the semiconductor CuO have been observed in absorption experiments up to a principal quantum number of n = 28 at millikelvin temperatures [1]. Here, we exte…

Distinct terahertz third-harmonic generation of many-body excitonic states
Changqing Zhu, Anneke Reinold, Patrick Pilch +6
The dynamics of an electron-hole plasma governed by strong Coulomb interaction is a challenging many-body problem.We report on experimental realization of electron-hole many-body s…
