Long-range hopping in a quasiperiodic potential weakens the non-Hermitian skin effect
Dechi Peng, Shujie Cheng, Gao Xianlong
In this paper, we investigate a non-Hermitian Aubry-André-Harper model characterized by power-law hoppings () and a quasi-periodic parameter , where denotes the pow…

Phase driven unconventional superradiance phase transition in non-Hermitian cascaded quantum Rabi cavities
Shujie Cheng, Shuai-Peng Wang, G. D. M. Neto +1
This study investigates phase-driven symmetry breaking leading to superradiance phase transitions in cascaded non-Hermitian quantum Rabi cavities. Non-Hermiticity is introduced via…
