Implication of giant photon bunching on quantum phase transition in the dissipative anisotropic quantum Rabi model

Tian Ye, Chen Wang, Qing-Hu Chen

We investigate the quantum phase transition in the dissipative anisotropic quantum Rabi model in the framework of quantum dressed master equation. From perspectives of both numeric…

Comment on `Parameter-dependent unitary transformation approach for quantum Rabi model'

Daniel Braak, Murray T. Batchelor, Qing-Hu Chen

We discuss the elementary errors in D.G. Zhang's [New. J. Phys. 23, 093014 (2021)] claimed exact solution of the quantum Rabi model. The erroneous solution is seen to be nothing mo…

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…

Possibility of superradiant phase transitions in coupled two-level atoms

Tao Liu, Yu-Yu Zhang, Qing-Hu Chen +1

Although the oscillator strength sum rule forbids the phase transition in ideal non-interacting two-level atoms systems, we present the possibility of the quantum phase transition…

General symmetry operators of the asymmetric quantum Rabi model

You-Fei Xie, Qing-Hu Chen

The true level crossing in the asymmetric quantum Rabi model without any obvious symmetry can be exhibited in the energy spectrum if the qubit bias is a multiple of the cavity freq…

Quantum phase transition of light in the dissipative Rabi-Hubbard lattice: A dressed-master-equation perspective

Tian Ye, Chen Wang, Qing-Hu Chen

In this work, we investigate the quantum phase transition of light in the dissipative Rabi-Hubbard lattice under the framework of the mean-field theory and quantum dressed master e…
