Effective Hamiltonian approach to the quantum phase transitions in the extended Jaynes-Cummings model
H. T. Cui, Y. A. Yan, M. Qin +1
The study of phase transitions in dissipative quantum systems based on the Liouvillian is often hindered by the difficulty of constructing a time-local master equation when the sys…
