The +/-J Spin Glass: Effects of Ground State Degeneracy | | Matteo Palassini

10 Dec 2000 | | Journal: | Phys.Rev.B63, 140408(R) (2001) | | Subject: | Disordered Systems and Neural Networks; Statistical Mechanics | cond-mat.dis-nn cond-mat.stat-mech | | Affiliation: | Univ. of California San Francisco, Univ. of California Santa Cruz | | Abstract: | We perform Monte Carlo simulations of the Ising spin glass at low temperature in three dimensions with a +/-J distribution of couplings. Our results display crossover scaling between T=0 behavior, where the order parameter distribution P(q) becomes trivial for L -> $infty$, and finite-T behavior, where the non-trivial part of P(q) has a much weaker dependence on the size L, and is possibly size independent. | | Source: | arXiv, cond-mat/0012161 | | Services: | Forum | Review | PDF | Favorites | |
