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…

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…
