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…
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, reve…
Many-body computing on Field Programmable Gate Arrays
Songtai Lv, Yang Liang, Yuchen Meng +5
A new implementation of many-body calculations is of paramount importance in the field of computational physics. In this study, we leverage the capabilities of Field Programmable G…
Signatures of quantum criticality in the complex inverse temperature plane
Yang Liu, Songtai Lv, Yang Yang +1
Concepts of the complex partition functions and the Fisher zeros provide intrinsic statistical mechanisms for finite temperature and real time dynamical phase transitions. We exten…
