Abstract:We present a high-precision Monte Carlo study of the π (3) spin theory on the lattice in π· = 4 dimensions. This model exhibits interesting dynamical features, in particular in the brokensymmetry phase, where suitable boundary conditions can be used to enforce monopole-like topological excitations. We investigate the Euclidean time propagation and the features of these excitations close to the critical point, where our numerical results show an excellent quantitative agreement with analytic predictions derive… Show more
