Vortex corrections to universal scaling of magnetic fluctuations in 2D XY model

Published 2002-07-19, updated 2002-12-17Version 2

The vortex contribution to the probability density function of longitudinal magnetization fluctuations is examined in finite 2D XY systems close to the Kosterlitz-Thouless-Berezinskii transition temperature. Within the temperature range studied their relevance is limited to rare fluctuations, where they increase the probability of events exceeding four standard deviations below the mean magnetization.
