Absence of collapse in quantum Rabi oscillations
Shu He, Yang Zhao, Qing-Hu Chen
We show analytically that the collapse and revival in the population dynamics of the atom-cavity coupled system under the rotating wave approximation (RWA), valid only at very weak…

Quantum criticality of the sub-Ohmic spin-boson model within displaced Fock states
Shu He, Liwei Duan, Qing-Hu Chen
The spin-boson model is analytically studied using displaced Fock states (DFS) without discretization of the continuum bath. In the orthogonal displaced Fock basis, the ground-stat…

Exact solvability, non-integrability, and genuine multipartite entanglement dynamics of the Dicke model
Shu He, Liwei Duan, Qing-Hu Chen
In this paper, the finite size Dicke model of arbitrary number of qubits is solved analytically in an unified way within extended coherent states. For the or Dicke mo…
