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…
Custodial chiral symmetry in a Su-Schrieffer-Heeger electrical circuit with memory
Massimiliano Di Ventra, Yuriy V. Pershin, Chih-Chun Chien
Custodial symmetries are common in the Standard Model of particle physics. They arise when quantum corrections to a parameter are proportional to the parameter itself. Here, we sho…
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…
Geometry-based circulation of local thermal current in quantum harmonic and Bose Hubbard systems
Palak Dugar, Chih-Chun Chien
A geometry-based mechanism for generating steady-state internal circulation of local thermal currents is demonstrated by harmonically coupled quantum oscillators formulated by the…
