Violation of Scaling in the Contact Process with Quenched Disorder
Ronald Dickman, Adriana G. Moreira
We study the two-dimensional contact process (CP) with quenched disorder (DCP), and determine the static critical exponents beta and nu_perp. The dynamic behavior is incompatible w…

Critical Dynamics of the Contact Process with Quenched Disorder
Adriana G. Moreira, Ronald Dickman
We study critical spreading dynamics in the two-dimensional contact process (CP) with quenched disorder in the form of random dilution. In the pure model, spreading from a single p…
