Understanding scale invariance in a minimal model of complex relaxation phenomena
Understanding scale invariance in a minimal model of complex relaxation phenomena
We report on the computer study of a lattice system that relaxes from a metastable state. Under appropriate nonequilibrium randomness, relaxation occurs by avalanches, i.e., the model evolution is discontinuous and displays many scales in a way that closely resembles the relaxation in a large number of complex systems in …
