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…
Computing quantum entanglement with machine learning
Andrea Bulgarelli, Elia Cellini, Karl Jansen +5
Entanglement calculations in quantum field theories are extremely challenging and typically rely on the replica trick, where the problem is rephrased in a study of defects. We demo…
Casimir effect in critical models from non-equilibrium Monte Carlo simulations
Andrea Bulgarelli, Michele Caselle, Alessandro Nada +1
vector models in three dimensions, when defined in a geometry with a compact direction and tuned to criticality, exhibit long-range fluctuations which induce a Casi…
Duality and entanglement in lattice gauge theories
Andrea Bulgarelli, Marco Panero
The study of entanglement in quantum field theories provides insight into universal properties which are typically challenging to extract by means of local observables. However, ca…
Approaches to the Inverse Problem
Luigi Del Debbio, Alessandro Lupo, Marco Panero +1
The analytical continuation of correlation functions from imaginary to real time is a crucial step in lattice gauge theories, and it challenges our ability to derive non-perturbati…
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…
Bayesian solution to the inverse problem and its relation to Backus-Gilbert methods

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…
Bayesian interpretation of Backus-Gilbert methods
Luigi Del Debbio, Alessandro Lupo, Marco Panero +1
The extraction of spectral densities from Euclidean correlators evaluated on the lattice is an important problem, as these quantities encode physical information on scattering ampl…
Entanglement entropy from non-equilibrium lattice simulations
Andrea Bulgarelli, Marco Panero
Entanglement entropy encodes important features of strongly interacting quantum many-body systems and gauge theories, but its analytical study is still limited to systems with high…
