CLUSTER ALGORITHM FOR A SOLID-ON-SOLID MODEL WITH CONSTRAINTS

[摘要] We adapt a cluster algorithm devised by us [H. G. Evertz et al., Phys. Lett. B 254, 185 (1991)] for simulations of solid-on-solid (SOS) models, to the body-centered SOS model. We note that this work is an application of a cluster algorithm on a model with constraints. The performance of this algorithm is studied in detail in both phases of the model, including a finite-size scaling analysis of the autocorrelations, and we find that critical slowing down is significantly reduced.
