Entanglement Entropy from Correlation Functions of Scalar Fields in and out of Equilibrium
Mrinal Kanti Sarkar, Saranyo Moitra, Rajdeep Sensarma
We show that odd order Rényi entropies of a system of interacting scalar fields can be calculated as the free energy of replicas of the system with additional q…

Instability of Laughlin FQH liquids into gapless power-law correlated states with continuous exponents in ideal Chern bands: rigorous results from plasma mapping
Saranyo Moitra, Inti Sodemann Villadiego
We investigate the fate of Laughlin's wave-function in ideal Chern bands which can be mapped to generalized zero Landau levels in spatially dependent magnetic fields. By exploiting…
