Giant bubbles of Fisher zeros in the quantum XY chain
Songtai Lv, Yang Liu, Erhai Zhao +2
We demonstrate an alternative approach based on complex-valued inverse temperature and partition function to probe quantum phases of matter with nontrivial spectra and dynamics. It…

Topological Feature of Real-time Fisher Zeros
Yuchen Meng, Yang Liu, Erhai Zhao +1
There are numerous methods to characterize topology and its boundary zero modes, yet their statistical mechanical properties have not received as much attention as other approaches…

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…
