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…

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…
