Diffusion-driven Coarsening: Lifshitz-Slyozov-Wagner Models of Ostwald Ripening and Rigorous Upper Bounds

Abstract:
Entropy increases, and at constant temperature, free energy decreases. Morphologically complex systems
dominated by interfacial energy exhibit coarsening behavior associated with dynamic scaling laws which
are not so well understood. I'll describe the classic LSW (Lifshitz-Slyozov-Wagner) mean-field model
of Ostwald ripening that serves as a paradigm for dynamic scaling, and discuss recent progress of Kohn
and Otto toward justifying dynamic scaling laws through rigorous upper bounds derived from underlying
diffuse-interface models.
