17 Oct 1997 | Subject: | Superconductivity; Disordered Systems and Neural Networks | cond-mat.supr-con cond-mat.dis-nn | Abstract: | Using Monte Carlo simulations, we study the properties of an elastic triangular lattice subject to a random background potential. As the cooling rate is reduced, we observe a rather sudden crossover between two different glass phases, one with exponential decay of correlations, the other with power-law decay. Contrary to predictions derived from continuum models, no evidence of a crossover in the mean-square displacement, B(r), from quadratic growth at small r, to logarithmic growth at large r is found. | Source: | arXiv, cond-mat/9710184 | Services: | Forum | Review | PDF | Favorites |
