Stability of High-Density Two-Dimensional Excitons against a Mott Transition in High Magnetic Fields Probed by Coherent Terahertz Spectroscopy
Qi Zhang, Yongrui Wang, Weilu Gao +5
We have performed time-resolved terahertz absorption measurements on photoexcited electron-hole pairs in undoped GaAs quantum wells in magnetic fields. We probed both unbound- and…

Collective, Coherent, and Ultrastrong Coupling of 2D Electrons with Terahertz Cavity Photons
Qi Zhang, Minhan Lou, Xinwei Li +5
Nonperturbative coupling of light with condensed matter in an optical cavity is expected to reveal a host of coherent many-body phenomena and states. In addition, strong coherent l…
