Interferometric geometry from symmetry-broken Uhlmann gauge group with applications to topological phase transitions
Hector Silva, Bruno Mera, Nikola Paunković
We provide a natural generalization of a Riemannian structure, i.e., a metric, recently introduced by Sjöqvist for the space of non degenerate density matrices, to the degenerate c…
Recoverability from direct quantum correlations
S. Di Giorgio, P. Mateus, B. Mera
We address the problem of compressing density operators defined on a finite dimensional Hilbert space which assumes a tensor product decomposition. In particular, we look for an ef…
Topologically protected quantization of work
Bruno Mera, Krzysztof Sacha, Yasser Omar
The transport of a particle in the presence of a potential that changes periodically in space and in time can be characterized by the amount of work needed to shift a particle by a…
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…
