Signatures of topological phase transition on a quantum critical line
Ranjith R Kumar, Nilanjan Roy, Y R Kartik +2
Recently topological states of matter have witnessed a new physical phenomenon where both edge modes and gapless bulk coexist at topological quantum criticality. The presence and a…

Entanglement entropy and out-of-time-order correlator in the long-range Aubry-André-Harper model
Nilanjan Roy, Auditya Sharma
We investigate the nonequilbrium dynamics of entanglement entropy and out-of-time-order correlator (OTOC) of noninteracting fermions at half-filling starting from a product state t…

Dynamics of spectral correlations in the entanglement Hamiltonian of the Aubry-André-Harper model
Aamna Ahmed, Nilanjan Roy, Auditya Sharma
We numerically study the evolution of spectral correlations in the entanglement Hamiltonian (EH) of non-interacting fermions in the Aubry-André-Harper (AAH) model. We analyze the t…
