Quantum phase transition of the one-dimensional compass model in a transverse magnetic field

Ke-Wei Sun, Qing-Hu Chen

The quantum phase transition (QPT) of the one-dimensional (1D) quantum compass model in a transverse magnetic field is studied in this paper. An exact solution is obtained by using…

Berry Phase and Fidelity in the Dicke model with $A^{2}$ term

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

The instability, so-called the quantum-phase-like transition, in the Dicke model with a rotating-wave approximation for finite $N$ atoms is investigated in terms of the Berry phase…
