Abstract
Extensive numerical simulations and scaling analysis are performed to investigate competitive growth between the linear and nonlinear stochastic dynamic growth systems,which belong to the Edwards-Wilkinson(EW)and Kardar-Parisi-Zhang(KPZ)universality classes,respectively.The linear growth systems include the EW equation and the model of random deposition with surface relaxation(RDSR),the nonlinear growth systems involve the KPZ equation and typical discrete models including ballistic deposition(BD),etching,and restricted solid on solid(RSOS).The scaling exponents are obtained in both the(1+1)-and(2+1)-dimensional competitive growth with the nonlinear growth probability p and the linear proportion 1-p.Our results show that,when p changes from 0 to 1,there exist non-trivial crossover effects from EW to KPZ universality classes based on different competitive growth rules.Furthermore,the growth rate and the porosity are also estimated within various linear and nonlinear growths of cooperation and competition.
