Phase transitions of the Dicke model: a unified perspective
Pragna Das, Auditya Sharma
The Dicke model exhibits a variety of phase transitions. The quantum phase transition from the normal phase to the super-radiant phase is marked by a dramatic change in the scaling…
Fano Resonances in Quantum Transport with Vibrations
Ajith Ramachandran, Michael Genkin, Auditya Sharma +3
Quantum mechanical scattering involving continuum states coupled to a scatterer with a discrete spectrum gives rise to Fano resonances. Here we consider scatterers that possess int…
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…
