Abstract:
We introduce a stochastic growth model where the growth is controlled by a temperaturelike parameter T. The model shows various types of dynamical behavior as T changes from 0 to infinity. For T=0 the growth process belongs to the quenched Kardar-Parisi-Zhang (KPZ) universality class, whereas it belongs to the Edwards-Wilkinson (EW) universality class for T=infinity. In the intermediate range 0
