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 criticality of the Rabi-Stark model at finite frequency ratios
Xiang-You Chen, You-Fei Xie, Qing-Hu Chen
In this paper, we analyze the quantum criticality of the Rabi-Stark model at finite ratios of the qubit and cavity frequencies in terms of the energy gap, the order parameter, as w…
