Semiclassical approach to the quantum Loschmidt echo in deep quantum regions: from validity to breakdown
Pinquan Qin, Qian Wang, Wen-ge Wang
Semiclassical results are usually expected to be valid in the semiclassical regime. An interesting question is, in models in which appropriate effective Planck constants can be int…

Scaling behavior for a class of quantum phase transitions
Wen-ge Wang, Pinquan Qin, Qian Wang +2
We show that for quantum phase transitions with a single bosonic zero mode at the critical point, like the Dicke model and the Lipkin-Meshkov-Glick model, metric quantities such as…
