A Cluster Algorithm for the Z2 Kalb-Ramond Model
P. K. Coyle, I. G. Halliday
Abstract
A cluster algorithm is presented for the Z2 Kalb-Ramond plaquette model in four dimensions which dramatically reduces critical slowing. The critical exponent z is reduced from z>2 (standard Metropolis algorithm) to z= 0.320.06. The Cluster algorithm updates the monopole configuration known to be responsible for the second order phase transition.
