Study of a microcanonical algorithm on the J spin glass model in d=3
J. J. Ruiz-Lorenzo, C. L. Ullod
Abstract
We consider a microcanonical local algorithm to be applied on the J spin glass model. We have compared the results coming from a microcanonical Monte Carlo simulation with those from a canonical one: Thermalization times, spin glass susceptibilities and Binder parameters. For a fixed lattice size we found different results between the two thermodynamic ensembles, which tend to vanish at bigger volumes. Moreover, microcanonical thermalization times are longer than the canonical ones. Finally we have checked that one of the Guerra relations is satisfied with good precision for the two largest lattices.
