Scaling flow-based approaches for topology sampling in $\mathrm{SU}(3)$ gauge theory

ArXi:2510.25704v2 Announce Type: replace-cross We develop a methodology based on out-of-equilibrium simulations to mitigate topological freezing when approaching the continuum limit of lattice gauge theories. We reduce the autocorrelation of the topological charge employing open boundary conditions, while removing exactly their unphysical effects using a non-equilibrium Monte Carlo approach in which periodic boundary conditions are gradually switched on.
