Investigation of the Critical Behavior of the Critical Point of the Z2 Gauge Lattice

We investigate, through Monte-Carlo simulations, the nature of the second order point in a $Z_2$ (Bosonic) + $Z_2$ gauge theory in four dimensions. Detailed analysis of the critical exponents point to the Ising universality class. Relevancy to extended models and possible Non-Gaussian behavior is discussed.

A Cluster Algorithm for the $Z_2$ Kalb-Ramond Model

A cluster algorithm is presented for the $Z_2$ 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 $z= 0.32\pm0.06$. The Cluster algorithm updates the monopole configuration known to be responsible for the second order phase transition.
