| Abstract |
Advanced Monte Carlo simulations of magnetisation and susceptibility in 3D XY model is performed at two different coupling constants completing our previous simulation results with additional data points and extending the range of the external field to twice smaller values (h ⥠0.00015625). The simulated maximal lattices sizes also are increased from L = 384 to L = 512. Our aim is an improved estimation of the exponent, describing the Goldstone mode singularity. Our best estimate of this exponent 0.555(17) is extracted from the analysis of effective exponents determined from local fits of the susceptibility data. We report also the values of spontaneous magnetisation. |
