Extensively degenerate superradiant phase in a giant-atom quantum Rabi ring
Shu He, Li-Wei Duan
We show that an -site quantum Rabi ring with matched giant-atom couplings has degenerate superradiant configurations as the atomic-to-cavity frequency ratio tends…
Excitation Gap of a Confined Chiral Mode Measures Critical Zero-Point Fluctuations
Shu He, Liwei Duan
Where uniform and chiral superradiant boundaries meet in a quantum Rabi ring, the quadratic theory leaves a degenerate chiral ladder with finite radial width. We show that adding o…
Nonequilibrium energy transport in driven-dissipative quantum systems
Junran Kong, Yuwei Lu, Huan Liu +2
Nonequilibrium energy transport serves as one of fundamental problems in quantum thermodynamics and quantum technologies. Driven quantum master equation in the dressed picture prov…
Analytical Study of the Non-Hermitian Semiclassical Rabi Model
Yibo Liu, Liwei Duan, Qing-Hu Chen
The symmetric semiclassical Rabi model explores the fundamental interaction between a two-level atom and a classical field, revealing novel phenomena in open systems…
Vacuum Rabi Splitting and Quantum Fisher Information of a Non-Hermitian Qubit in a Single-Mode Cavity
Yi-Cheng Wang, Jiong Li, Li-Wei Duan +1
A natural extension of the non-Hermitian qubit is to place it in a single-mode cavity. This setup corresponds to the quantum Rabi model (QRM) with a purely imaginary bias on the qu…
-symmetric quantum Rabi model: Solutions and exceptional points
Jiong Li, Yi-Cheng Wang, Li-Wei Duan +1
The -symmetric non-Hermitian quantum Rabi model (QRM) with imaginary coupling is solved using the Bogoliubov operators approach. A transcendental function responsible…
