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…
Probing Band-center Anomaly with the Kernel Polynomial Method
N. A. Khan, Syed Tahir Amin
We investigate the anomalous behavior of localization length of a non-interacting one-dimensional Anderson model at zero temperature. We report numerical calculations of the Thoule…
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…
Practical Quantum Teleportation of an Unknown Quantum State
Syed Tahir Amin, Aeysha Khalique
We develop a theory to teleport an unknown quantum state using entanglement between two distant parties. Our theory takes into account experimental limitations due to contribution…
