Distribution of fidelity zeros in two-band topological models
Siyan Lin, Zhen-Yu Zheng, Shu Chen
We investigate the distribution of fidelity zeros in two-band topological models by extending the phase transition driving parameter into the complex plane. Within the biorthogonal…
Emergence of long-range entanglement and odd-even effect in periodic generalized quantum cluster models
Zhen-Yu Zheng, Shu Chen
We investigate the entanglement properties in a generalized quantum cluster model under periodic boundary condition. By evaluating the quantum conditional mutual information entrop…
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…
Characterizing dynamical behaviors in topological open systems with boundary dissipations
Zhen-Yu Zheng, Xueliang Wang, Shu Chen
We investigate the dynamics of the Su-Schrieffer-Heeger model with boundary dissipations described by Lindblad master equations and unravel distinct dynamical features in the topol…
