摘要: Abstract The critical properties of systems with quenched disorder, short-range correlated in some directions and decaying as a power law the remaining ones, are studied within double-expansion renormalization group approach. We find that different regimes occur, depending on symmetry index disorder parameters, anisotropy does not influence Fisher correlation length exponents to one-loop approximation.
