The monopole plasma resonance: a smoking gun of 3D quantum spin liquids
Anish Koley, Saranyo Moitra, Inti Sodemann Villadiego
Certain 3D spin liquids, such as those arising in dipolar quantum spin ice, have an emergent monopole which is the source of an emergent magnetic field that transforms under…
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…
Signature of Criticality in Angular Momentum Resolved Entanglement of Scalar Fields in
Mrinal Kanti Sarkar, Saranyo Moitra, Rajdeep Sensarma
The scaling of entanglement entropy with subsystem size fails to distinguish between gapped and gapless ground state of a scalar field theory in dimensions. We show that the…
Building Entanglement Entropy out of Correlation Functions for Interacting Fermions
Saranyo Moitra, Rajdeep Sensarma
We provide a prescription to construct Rényi and von Neumann entropy of a system of interacting fermions from a knowledge of its correlation functions. We show that Rényi entanglem…
Entanglement Entropy of Fermions from Wigner Functions: Excited States and Open Quantum Systems
Saranyo Moitra, Rajdeep Sensarma
We formulate a new ``Wigner characteristics'' based method to calculate entanglement entropies of subsystems of Fermions using Keldysh field theory. This bypasses the requirements…
Hybrid scheme for factorization: Factoring 551 using a 3-qubit NMR quantum adiabatic processor
Soham Pal, Saranyo Moitra, V. S. Anjusha +2
Quantum processors are potentially superior to their classical counterparts for many computational tasks including factorization. Circuit methods as well as adiabatic methods have…
