Probing the excited-state quantum phase transition through statistics of Loschmidt echo and quantum work

Qian Wang, H. T. Quan

By analyzing the probability distributions of the Loschmidt echo (LE) and quantum work, we examine the nonequilibrium effects of a quantum many-body system, which exhibits an excit…
