Enhancement of the critical slowing down influenced by extended defects
arXiv:cond-mat/0508523
Abstract
We study an influence of the quenched extended defects on the critical dynamics of the d=3-dimensional systems with m-component non-conserved order parameter (model A dynamics). Considering defects to be correlated in ε_d dimensions and randomly distributed in d-ε_d dimensions we obtain reliable numerical values for the critical exponents governing divergence of the relaxation time as function of m and ε_d.
