Spin-Valley Relaxation of Rydberg Excitons
V. Jindal, K. Mourzidis, M. Semina +8
Rydberg excitons, characterized by large spatial extension and reduced electron-hole overlap, must have a spin-valley dynamics different from that of ground state excitons. Here we…

Emission Dynamics of Rydberg Excitons in : Distinguishing Second Harmonic Generation from Secondary Emission
Kerwan Morin, Poulab Chakrabarti, Delphine Lagarde +5
Rydberg excitons in simultaneously give rise to two very different optical responses under resonant two-photon excitation: a coherent second-harmonic signal mediat…

Direct measurement of the lifetime and coherence time of Cu2O Rydberg excitons
Poulab Chakrabarti, Kerwan Morin, Delphine Lagarde +2
Rydberg states of excitons are promising quantum objects to engineer giant nonlinearities in a solid-state system. For this purpose, a deeper understanding of the dynamics of Rydbe…
