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…

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…

Closed dynamical recursion equations for correlation functions and the application on the construction of Liouvillian spectrum in Lindbladian systems
Xueliang Wang, Shu Chen
For an open quantum system described by the Lindblad equation, full characterization of its dynamics typically needs the knowledge of the Liouvillian spectrum and correlation funct…
