Strong disorder RG approach of random systems
There is a large variety of quantum and classical systems in which the quenched disorder
plays a dominant rôle over quantum, thermal, or stochastic fluctuations: these systems …

Griffiths phase and critical behavior of the two-dimensional Potts models with long-range correlated disorder
C Chatelain - Physical Review E, 2014 - APS
The q-state Potts model with long-range correlated disorder is studied by means of large-
scale Monte Carlo simulations for q= 2, 4, 8, and 16. Evidence is given of the existence of a …
