7 Sep 2001 | | Journal: | Phys. Rev. B, 65, 134404 (2002) | | Subject: | Statistical Mechanics; Disordered Systems and Neural Networks | cond-mat.stat-mech cond-mat.dis-nn | | Abstract: | We present an exact algorithm for finding all the ground states of the two-dimensional Edwards-Anderson $pm J$ spin glass and characterize its performance. We investigate how the ground states change with increasing system size and and with increasing antiferromagnetic bond ratio $x$. We find that that some system properties have very large and strongly non-Gaussian variations between realizations. | | Source: | arXiv, cond-mat/0109136 | | Services: | Forum | Review | PDF | Favorites | |
