Superradiant phase transitions in the quantum Rabi model: Overcoming the no-go theorem through anisotropy
Tian Ye, Yan-Zhi Wang, Xiang-You Chen +2
Although the superradiant phase transition (SRPT) is prohibited in the paradigmatic quantum Rabi model due to the no-go theorem caused by the term, we demonstrate tw…

Quantum phase transition in the one-dimensional Dicke-Hubbard model with coupled qubits
Shu He, Li-Wei Duan, Yan-Zhi Wang +2
We study the ground state phase diagram of a one-dimensional two qubits Dicke-Hubbard model with XY qubit-qubit interaction. We use a numerical method combing the cluster mean-fiel…

symmetry of a square-wave modulated two-level system
Liwei Duan, Yan-Zhi Wang, Qing-Hu Chen
We study a non-Hermitian two-level system with square-wave modulated dissipation and coupling. Based on the Floquet theory, we achieve an effective Hamiltonian from which the bound…
