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 ac…

Flow-Based Sampling for Entanglement Entropy and the Machine Learning of Defects
Andrea Bulgarelli, Elia Cellini, Karl Jansen +5
We introduce a novel technique to numerically calculate Rényi entanglement entropies in lattice quantum field theory using generative models. We describe how flow-based approaches…

Duality transformations and the entanglement entropy of gauge theories
Andrea Bulgarelli, Marco Panero
The study of entanglement in gauge theories is expected to provide insights into many fundamental phenomena, including confinement. However, calculations of quantities related to e…
