| Abstract: | We propose a novel Monte Carlo scheme to study the late-time dynamics of a 2D hard sphere fluid, modeled by a tethered network of hard spheres. Fluidity is simulated by breaking and reattaching the flexible tethers. We study the diffusion of a tagged particle, and show that the velocity autocorrelation function has a long-time t-1 tail. We investigate the dynamics of phase separation of a binary fluid at late times, and show that the domain size R\(t\) grows as t1/2 for high-viscosity fluids with a crossover to t2/3 for low-viscosity fluids. Our scheme can accommodate particles interacting with a softer pair potential V\(r\). |
