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…

Effective Hamiltonian approach to the exact dynamics of open system by complex discretization approximation for environment
H. T. Cui, Y. A. Yan, M. Qin +1
The discretization approximation method commonly used to simulate the dynamics of quantum system coupled to the environment in continuum often suffers from the periodically partial…
