Franzese, GiancarloConiglio, Antonio, 1940-2011-07-072011-07-0719981063-651Xhttps://hdl.handle.net/2445/18873We have studied the Potts spin glass with two-state Ising spins and s -state Potts variables using a cluster Monte Carlo dynamics. The model recovers the ± J Ising spin glass (SG) for s = 1 and exhibits for all s a SG transition at T SG ( s ) and a percolation transition at higher temperature T p ( s ) . We have shown that for all values of s ≠ 1 at T p ( s ) there is a thermodynamic transition in the universality class of a ferromagnetic s -state Potts model. The efficiency of the cluster dynamics is compared with that of standard spin-flip dynamics.7 p.application/pdfeng(c) American Physical Society, 1998Model d'IsingTransformacions de fase (Física estadística)Mecànica estadísticaIsing modelPhase transformations (Statistical physics)Statistical mechanicsinfo:eu-repo/semantics/article513984info:eu-repo/semantics/openAccess
