Entanglement and reciprocal dynamics of the Barnett and Einstein-de Haas responses in a quantum spin-rotor model
Saikat Banerjee, Holger Fehske
We study the reciprocal Barnett and Einstein--de Haas effects in an exactly solvable quantum spin--rotor model that conserves the total angular momentum. For a single spin-, t…

Axionic tunneling from a topological Kondo insulator
Saikat Banerjee, Anuva Aishwarya, Fei Liu +4
Discoveries over the past two decades have revealed the remarkable ability of quantum materials to emulate relativistic properties of the vacuum, from Dirac cones in graphene to Di…

Resolving the Thermal Paradox: Many-body localization or fractionalization?
Saikat Banerjee, Piers Coleman
Thermal measurements of heat capacity and thermal conductivity in a wide range of insulators and superconductors exhibit a ``thermal paradox": a large linear specific heat reminisc…
