Coarse-graining a restricted solid-on-solid model.
A procedure suggested by Vvedensky for obtaining continuum equations as the coarse-grained limit of discrete models is applied to the restricted solid-on-solid model with both adsorption and desorption. Using an expansion of the master equation, discrete Langevin equations are derived; these agree quantitatively with direct simulation of the model. From these, a continuum differential equation ...
متن کاملRoughening transition of a restricted solid-on-solid model in the directed percolation universality class.
We carried out a finite-size scaling analysis of the restricted solid-on-solid version of a recently introduced growth model that exhibits a roughening transition accompanied by spontaneous symmetry breaking. The dynamic critical exponent of the model was calculated and found to be consistent with the universality class of the directed percolation process in a symmetry-broken phase with a cross...
متن کاملUniversality of (2+1)-dimensional restricted solid-on-solid models.
Extensive dynamical simulations of restricted solid-on-solid models in D=2+1 dimensions have been done using parallel multisurface algorithms implemented on graphics cards. Numerical evidence is presented that these models exhibit Kardar-Parisi-Zhang surface growth scaling, irrespective of the step heights N. We show that by increasing N the corrections to scaling increase, thus smaller step-si...
متن کاملSolid ± solid and liquid ± solid phase equilibria for the restricted primitive model
A Monte Carlo simulation study is made of the phase diagram of the restricted primitive model and of the solid± liquid and solid± solid phase coexistence curves in particular. At low temperatures, there is liquid± bcc coexistence and with increasing density there is bcc± fcc coexistence. These coexistence curves end in a triple point (liquid± bcc ± fcc) above which only liquid± fcc coexistence ...
متن کاملCoarse graining
Multiscale simulations For nearly all systems of interest to us, the most transferrable and fundamental description of matter is one that invokes quantum mechanics. At the highest level of accuracy, this amounts to solving Schrodinger’s equation for all of the subatomic particles in a system. Computationally, many approximations need to be made in order to use ab initio methods, and even these ...
