Evidence for existence of many pure ground states in 3d $pm J$ Spin Glasses | | Alexander K. Hartmann
; | | Date: |
22 Apr 1997 | | Journal: | Europhys. Lett. 40, 429 (1997) | | Subject: | Disordered Systems and Neural Networks | cond-mat.dis-nn | | Abstract: | Ground states of 3d EA Ising spin glasses are calculated for sizes up to $14^3$ using a combination of genetic algorithms and cluster-exact approximation . The distribution $P(|q|)$ of overlaps is calculated. For increasing size the width of $P(|q|)$ converges to a nonzero value, indicating that many pure ground states exist for short range Ising spin glasses. | | Source: | arXiv, cond-mat/9704187 | | Services: | Forum | Review | PDF | Favorites | |
