Anomalous topological superradiant phases
You-Qi Lu, Yu-Yu Zhang, Zi-Xiang Hu
We present a novel set of light-matter topology realized by implementing a finite-component quantum Rabi array with a photonic analog of the Su-Schrieffer-Heeger (SSH) configuratio…
Higher-order exceptional lines in a non-Hermitian JaynesCummings triangle
Hao Chen, Xiao Qin, Jian-Jun Dong +2
Higher-order exceptional points (EPs) in non-Hermitian systems showcase diverse physical phenomena but require more parameter space freedom or symmetries. It leads to a challenge f…
Meissner-Like Currents of Photons in Anomalous Superradiant Phases
Linjun Li, Pengfei Huang, Zi-Xiang Hu +1
We present Meissner-like photon currents in a quantum Rabi zigzag chain under staggered synthetic magnetic fields. The ground state of the Meissner superradiant phase hosts persist…
Analytically solvable model to the spin Hall effect with Rashba and Dresselhaus spin-orbit couplings
Rui Zhang, Yuan-Chuan Biao, Wen-Long You +2
When the Rashba and Dresslhaus spin-orbit coupling are both presented for a two-dimensional electron in a perpendicular magnetic field, a striking resemblance to anisotropic quantu…
