A. Vespignani et al., DYNAMICALLY DRIVEN RENORMALIZATION-GROUP APPLIED TO SELF-ORGANIZED CRITICAL SYSTEMS, International journal of modern physics b, 12(12-13), 1998, pp. 1407-1417
The Dynamically Driven Renormalization Group is a general framework de
veloped to study the critical properties of nonequilibrium systems wit
h stationary states. In particular this renormalization scheme allows
the systematic analysis of several models showing self-organised criti
cality in terms of usual concepts of phase transitions and critical ph
enomena.
