Exact Fisher zeros and thermofield dynamics across a quantum critical point
By setting the inverse temperature β loose to occupy the complex plane, Fisher showed that the zeros of the complex partition function Z, if approaching the real β axis, reveal a thermodynamic phase transition. More recently, Fisher zeros were used to mark the dynamical phase transition in quench dy...
