Title:Motion of Interfaces in a Lattice Model for Phase and Grain Boundaries
Abstract: The modeling and analysis of phase and grain boundary structures and evolutions have a long history in materials science. Besides the intrinsic interests in their own studies, they in turn determine the macroscopic behavior of materials. Variational formulation and curvature driven flows has lead to many understanding at the continuum level. In this talk, we will extend some of these ideas to interfaces in lattice environments which mimic atomic interactions. New features include interfaces between patterns and stick-slip phenomena. Dynamically, this can be tied to evolutions on energy landscapes with lots of local minima
