Vortex Mass in the Three-Dimensional O(2) Scalar Theory
Author(s): Gesualdo Delfino, Walter Selke, and Alessio Squarcini
We study the spontaneously broken phase of the $XY$ model in three dimensions, with boundary conditions enforcing the presence of a vortex line. Comparing Monte Carlo and field-theoretic determinations of the magnetization and energy density profiles, we numerically determine the mass of the vortex ...
