Vortex corrections to universal scaling of magnetic fluctuations in 2D XY model
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.Comment: 6 pages, 4 figures. Refs adde
