The fate of dynamical phase transitions at finite temperatures and in open systems
N. Sedlmayr, M. Fleischhauer, J. Sirker
When a quantum system is quenched from its ground state, the time evolution can lead to non-analytic behavior in the return rate at critical times . Such dynamical phase trans…

Commuting Heisenberg operators as the quantum response problem: Time-normal averages in the truncated Wigner representation
B. Berg, L. I. Plimak, A. Polkovnikov +3
The applicability of the so-called truncated Wigner approximation (-W) is extended to multitime averages of Heisenberg field operators. This task splits naturally in two. Firstly,…
