Multiple ground-state instabilities in the anisotropic quantum Rabi model
Xiang-You Chen, Liwei Duan, Daniel Braak +1
In this work, the anisotropic variant of the quantum Rabi model with different coupling strengths of the rotating and counter-rotating wave terms is studied by the Bogoliubov opera…
Single-photon scattering controlled by an imperfect cavity
Liwei Duan, Qing-Hu Chen
We study the single-photon transport in the coupled-resonator waveguide (CRW) controlled by an imperfect cavity. A Lorentzian spectrum is introduced to describe the dissipation. We…
symmetry of a square-wave modulated two-level system
Liwei Duan, Yan-Zhi Wang, Qing-Hu Chen
We study a non-Hermitian two-level system with square-wave modulated dissipation and coupling. Based on the Floquet theory, we achieve an effective Hamiltonian from which the bound…
Quantum Zeno effect in the multimode quantum Rabi model
Shu He, Chen Wang, Xue-Zao Ren +2
We study the quantum Zeno effect (QZE) and quantum anti-Zeno effect (QAZE) of the multimode quantum Rabi model(MQRM). We derive an analytic expression for the decay rate of the sur…
Quantum Rabi-Stark model: Solutions and exotic energy spectra
You-Fei Xie, Liwei Duan, Qing-Hu Chen
The quantum Rabi-Stark model, where the linear dipole coupling and the nonlinear Stark-like coupling are present on an equal footing, are studied within the Bogoliubov operators ap…
The mixed quantum Rabi model
Liwei Duan, You-Fei Xie, Qing-Hu Chen
The analytical exact solutions to the mixed quantum Rabi model (QRM) including both one- and two-photon terms are found by using Bogoliubov operators. Transcendental functions in t…
