Refraction-induced transverse charge transport
Ronika Sarkar, Arka Bandyopadhyay, Awadhesh Narayan +1
We introduce a mechanism that produces a Hall-like transverse response in time-reversal-invariant materials, driven entirely by geometric effects. Specifically, we demonstrate that…
Floquet multiple exceptional points with higher-order skin effect
Gaurab Kumar Dash, Subhendu Kumar Patra, Diptiman Sen +1
We investigate the rich non-equilibrium physics arising in periodically driven open quantum systems, specifically those realized within microcavity resonators, whose dynamics are g…
Metric response of relative entropy: A universal indicator of quantum criticality
Pritam Sarkar, Diptiman Sen, Arnab Sen
The information-geometric origin of fidelity susceptibility and its utility as a universal probe of quantum criticality in many-body settings have been widely discussed. Here we ex…
Topological phase transition through tunable nearest-neighbor interactions in a one-dimensional lattice
Rajashri Parida, Diptiman Sen, Tapan Mishra
We investigate the phase diagram of a one-dimensional model of hardcore bosons or spinless fermions with tunable nearest-neighbor interactions. By introducing alternating repulsive…
