Title: Topological excitations in statistical field theory at the upper critical dimension
(Submitted on 22 Dec 2020 (v1), last revised 24 Mar 2021 (this version, v2))
Abstract: We present a high-precision Monte Carlo study of the classical Heisenberg model in four dimensions, showing that in the broken-symmetry phase it supports topological, monopole-like excitations, whose properties confirm previous analytical predictions derived in quantum field theory. We discuss the relevance of these findings and their possible experimental applications in condensed-matter physics.
