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…

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…

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…
