Finite-size scaling analysis in the two-photon Dicke model
Xiang-You Chen, Yu-Yu Zhang
The Hamiltonian of the two-photon Dicke model is diagonalized for the normal phase and super-radiant phase beyond the mean-field method respectively, giving the critical coupling s…

Analytical solutions by squeezing to the anisotropic Rabi model in the nonperturbative deep-strong coupling regime
Yu-Yu Zhang, Xiang-You Chen
A novel, unexplored nonperturbative deep-strong coupling (npDSC) achieved in superconducting circuits has been studied in the anisotropic Rabi model by the generalized squeezing ro…
