Exact solvability of the quantum Rabi models within Bogoliubov operators
Qing-Hu Chen, Chen Wang, Shu He +2
The quantum Rabi model can be solved exactly by the Bargmann transformation from real coordinate to complex variable recently [Phys. Rev. Lett. \textbf{107}, 100401 (2011)]. By the…

Unified analytical treatments to qubit-oscillator systems
Shu He, Yu-Yu Zhang, Qing-Hu Chen +3
An effective scheme within two displaced bosonic operators with equal positive and negative displacements is extended to study qubit-oscillator systems analytically in an unified w…

Jaynes-Cummings model: What emerges first beyond the rotating-wave approximation?
Shu He, Qing-Hu Chen, Xue-Zao Ren +2
The Jaynes-Cummings model without the rotating-wave approximation can be solved exactly by extended Swain's ansatz with the conserved parity. The analytical approximations are then…
