Intrinsic Width of the Flux Tube as a tool to explore confining mechanisms in Lattice Gauge Theories
Michele Caselle, Elia Cellini, Alessandro Nada +2
We study the profile of the flux tube in the SU(2) gauge model in 2+1 dimensions, with a particular attention to the so called "intrinsic width" which drives the exponential decay…
Intrinsic Width of the flux tube in 2+1 dimensional Yang-Mills theories
Lorenzo Verzichelli, Michele Caselle, Elia Cellini +2
We present our updated results on the intrinsic width of the profile of the flux tube in (2+1)-dimensional Yang-Mills theory with SU(2) gauge group. We identify the intrinsic width…
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…
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…
Studying Effective String Theory using deep generative models
Michele Caselle, Elia Cellini, Alessandro Nada
Effective String Theory (EST) offers a robust non-perturbative framework for describing confinement in Yang-Mills theory by treating the confining flux tube between a static quark-…
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…
