Cluster Monte Carlo study of magnetic dipoles

Abstract

We implement a cluster-update Monte Carlo algorithm to simulate magnetic dipoles of the XY-spin type confined in a two-dimensional plane. The long-range character and anisotropy in the dipole interaction are handled by using the Luijten-Blöte algorithm and the Dotsenko-Selke-Talapov algorithm, respectively. We have checked the performance of this cluster-update algorithm in comparison to the Metropolis algorithm and found that it equilibrated the system faster in terms of the number of flipped spins, although the overall computational complexity of the problem remained the same.
