Fidelity and Uhlmann connection analysis of topological phase transitions in two dimensions

S. T. Amin, B. Mera, C. Vlachou +2

We study the behaviour of the fidelity and the Uhlmann connection in two-dimensional systems of free fermions that exhibit non-trivial topological behavior. In particular, we use t…

Topological response of gapped fermions to a $U (1)$ Gauge field

B. Mera

We present a detailed path integral derivation of the topological response of gapped free fermions, in $2 + 1$ dimensions, to an external $U (1)$ Gauge field. The well-known Ha…
