Simulating Glassy Systems with Patchwork Dynamics

Creighton Thomas
Department of Physics, Syracuse University

Glassy dynamics in disordered materials prohibits the direct simulation of their nonequilibrium behavior at large scales. In this talk, I present patchwork dynamics, a technique in which local Monte Carlo updates are replaced by exact equilibration on patches at a given length scale. In cases where fast equilibration or ground state algorithms exist, this technique can immensely speed up simulations. This allows us to probe the long-time dynamics of glassy materials and see behaviors, such as memory effects, which are poorly understood and had not been observed in simulations.
