Vanishing k-space fidelity and phase diagram's bulk-edge-bulk correspondence
P. D. Sacramento, B. Mera, N. Paunkovic
The fidelity between two infinitesimally close states or the fidelity susceptibility of a system are known to detect quantum phase transitions. Here we show that the k-space fideli…
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…
Entanglement-induced deviation from the geodesic motion in quantum gravity
Francisco Pipa, Nikola Paunkovic, Marko Vojinovic
We study the derivation of the effective equation of motion for a pointlike particle in the framework of quantum gravity. Just like the geodesic motion of a classical particle is a…
