26 Aug 2006 | Subject: | Disordered Systems and Neural Networks | Abstract: | Numerical results up to 42nd order of replica symmetry breaking (RSB) are used to predict the singular structure of the SK spin glass at T=0. We confirm predominant single parameter scaling and derive corrections for the T=0 order function q(a), related to a Langevin equation with pseudotime 1/a. a=0 and a=infty are shown to be critical points for infty-RSB, associated with two discrete spectra of Parisi block size ratios, attached to a continuous spectrum. Finite-RSB-size-scaling, associated exponents, and T=0-energy are obtained with unprecedented accuracy. | Source: | arXiv, cond-mat/0608581 | Services: | Forum | Review | PDF | Favorites |
