Chiral Vacuum Engineering of Quantum Hall Matter
Kiran M. Kulkarni, Andrey Baydin, Motoaki Bamba +3
We reveal that a chiral cavity distinguishes the resonant and antiresonant interactions between a two-dimensional electron gas and the cavity vacuum. For co-rotating helicities, th…
Terahertz anomalous Hall effect in magnetic Weyl semimetal CoSnS
Ashutosh Singh, Hongjing Xu, Xielin Wang +6
Time-reversal-symmetry-broken Weyl semimetals are known to have at least two nodes in their electronic band structure, separated in momentum space and acting as sources and sinks o…
Floquet Engineering of a Quasiequilibrium Superradiant Phase Transition in Landau Polaritons
Wen-Hua Wu, Fuyang Tay, Mengqian Che +3
Superradiant phase transitions (SRPTs), characterized by photon condensation and macroscopic matter polarization, are forbidden in equilibrium for homogeneous fields by no-go theor…
Observation of Photoinduced Terahertz Gain in GaAs Quantum Wells: Evidence for Radiative Two-Exciton-to-Biexciton Scattering
X. Li, K. Yoshioka, Q. Zhang +9
We have observed photoinduced negative optical conductivity, or gain, in the terahertz frequency range in a GaAs multiple-quantum-well structure in a strong perpendicular magnetic…
