Critical spectrum of the anisotropic two-photon quantum Rabi model
Jiong Li, Daniel Braak, Qing-Hu Chen
The anisotropic two-photon quantum Rabi model is studied using the Bogoliubov operator approach. The doubly degenerate exceptional states are identified through analytical methods.…

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…
