Detecting Many-Body Scars from Fisher Zeros
Yuchen Meng, Songtai Lv, Yang Liu +3
The far-from-equilibrium dynamics of certain interacting quantum systems still defy precise understanding. One example is the so-called quantum many-body scars (QMBSs), where a set…

Exact Fisher zeros and thermofield dynamics across a quantum critical point
Yang Liu, Songtai Lv, Yuchen Meng +3
By setting the inverse temperature loose to occupy the complex plane, Fisher showed that the zeros of the complex partition function , if approaching the real axis, re…
