Boundary effects on the scaling of the superfluid density
N. Schultka, E. Manousakis
Abstract
We study numerically the influence of the substrate (boundary conditions) on the finite--size scaling properties of the superfluid density ρs in superfluid films of thickness H within the XY model employing the Monte Carlo method. Our results suggest that the jump ρs H/Tc at the Kosterlitz--Thouless transition temperature Tc depends on the boundary conditions.
