Many-body chaos and anomalous diffusion across thermal phase transitions in two dimensions
Sibaram Ruidas, Sumilan Banerjee
Chaos is an important characterization of classical dynamical systems. How is chaos linked to the long-time dynamics of collective modes across phases and phase transitions? We add…
Excess entropy and breakdown of semiclassical description of thermoelectricity in twisted bilayer graphene close to half filling
Bhaskar Ghawri, Phanibhusan S. Mahapatra, Shinjan Mandal +9
In moiré systems with twisted bilayer graphene (tBLG), the amplification of Coulomb correlation effects at low twist angles () is a result of nearly flat low-energy electronic b…
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…
