| Description |
Based on Ken Elder's 1993 paper: "Langevin simulations of nonequilibrium phenomena" Computers In Physics, vol. 7, no. 1, 1993, p.27-33.
Domains of ordered phase are created from an initially disordered phase due to thermal fluctuations. The domains coarsen as a function of time. Large domains grow at the expense of smaller ones because the free energy includes both bulk and surface terms. |
