Information geometry of quantum critical submanifolds: relevant, marginal and irrelevant operators
Bruno Mera, Nikola Paunković, Syed Tahir Amin +1
We analyze the thermodynamical limit of the quantum metric along critical submanifolds of theory space. Building upon various results previously known in the literature, we relate…
Information geometric analysis of long range topological superconductors
Syed Tahir Amin, Bruno Mera, Nikola Paunković +1
The Uhlmann connection is a mixed state generalisation of the Berry connection. The latter has a very important role in the study of topological phases at zero temperature. Closely…
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…
Dynamical phase transitions at finite temperature from fidelity and interferometric Loschmidt echo induced metrics
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +2
We study finite-temperature Dynamical Quantum Phase Transitions (DQPTs) by means of the fidelity and the interferometric Loschmidt Echo (LE) induced metrics. We analyse the associa…
The Uhlmann connection in fermionic systems undergoing phase transitions
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +1
We study the behaviour of the Uhlmann connection in systems of fermions undergoing phase transitions. In particular, we analyse some of the paradigmatic cases of topological insula…
Duality and topology
P. D. Sacramento, V. R. Vieira
Mappings between models may be obtained by unitary transformations with preservation of the spectra but in general a change in the states. Non- canonical transformations in general…
