Loschmidt echo zeros in finite-size quantum systems with linear quench
Zhen-Yu Zheng, Xudong Liu, Siyan Lin +2
Dynamical quantum phase transitions reveal singularities in quench dynamics, characterized by the emergence of Loschmidt echo zeros at critical times, which usually exist only in t…

Scale-free localization versus Anderson localization in unidirectional quasiperiodic lattices
Yu Zhang, Luhong Su, Shu Chen
Scale-free localization emerging in non-Hermitian physics has recently garnered significant attention. In this work, we explore the interplay between scale-free localization and An…
