Mapping twist fields to local operators via tensor networks
Andrea Bulgarelli, Marco Panero, Paolo Stornati +1
Twist fields are a powerful formal tool to compute Rényi entropies in quantum many-body systems, but their conventional formulation in tensor network states involves operations act…

Entanglement entropy from non-equilibrium Monte Carlo simulations
Andrea Bulgarelli, Marco Panero
We study the entanglement entropy in lattice field theory using a simulation algorithm based on Jarzynski's theorem. We focus on the entropic c-function for the Ising model in two…
