Abstract

We consider the spontaneously broken regime of the O(n) vector model in d = n + 1 space-time dimensions, with boundary conditions enforcing the presence of a topological defect line. Comparing theory and finite size dependence of one-point functions observed in recent numerical simulations we argue that the mass of the underlying topological quantum particle becomes infinite when d >= 4 .
