Renyi entanglement entropy of Fermi liquids and non-Fermi liquids: Sachdev-Ye-Kitaev model and dynamical mean field theories
Arijit Haldar, Surajit Bera, Sumilan Banerjee
We present a new method for calculating Renyi entanglement entropies for fermionic field-theories originating from microscopic Hamiltonians. The method builds on an operator identi…

Quench, thermalization and residual entropy across a non-Fermi liquid to Fermi liquid transition
Arijit Haldar, Prosenjit Haldar, Surajit Bera +2
We study the thermalization, after sudden and slow quenches, of an interacting model having a quantum phase transition from a Sachdev-Ye-Kitaev (SYK) non-Fermi liquid (NFL) to a Fe…
