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…
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…
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…
Ultrafast adiabatic passages in ultrastrongly coupled light-matter systems
Xun Gao, Liwei Duan, Pinghua Tang +4
We have obtained the solutions of the multimode quantum Rabi model when all modes have identical frequencies , including dark states with at least $(K=1,2,3,…
