Geometric phases of Topological Systems under Quench Process
Zhan Gao, Yan He
We study the time evolution of geometric phases of one dimensional topological models under the quench dynamics. Taking the Creutz ladder model as an example, it is found that the…
Particle and thermal transport through one dimensional topological systems via Lindblad formalism
Yan He, Chih-Chun Chien
We apply the Lindblad quantum master equation to two examples of one-dimensional topological systems, the Su-Schrieffer-Heeger (SSH) model and Kitaev chain, to study their particle…
Uhlmann holonomy against Lindblad dynamics of topological systems at finite temperatures
Yan He, Chih-Chun Chien
The Uhlmann phase, which reflects the holonomy as the purified state of a density matrix traverses a loop in the parameter space, has been used to characterize topological properti…
Proxy ensemble geometric phase and proxy index of time-reversal invariant topological insulators at finite temperatures
Aixin Pi, Ye Zhang, Yan He +1
The ensemble geometric phase (EGP) has been proposed as a topological indicator for finite-temperatures systems. The ensemble Wilson loop, or the transfer matrix, contains the cruc…
Quantum Interference Transport in two-dimensional Semi-Dirac Semimetals
Shihao Bi, Yiting Deng, Yan He +1
Semi-Dirac semimetals have received enthusiastic research both theoretically and experimentally in the recent years. Due to the anisotropic dispersion, its physical properties are…
Comparison of finite-temperature topological indicators based on Uhlmann connection
Ye Zhang, Aixin Pi, Yan He +1
Two indicators of finite-temperature topological properties based on the Uhlmann connection, one generalizing the Wilson loop to the Uhlmann-Wilson loop and the other generalizing…
