Title: Obstacle-Ginzburg-Landau Functionals

Abstract: We will discuss a variation of the Ginzburg-Landau functional, involving a so-called "double-obstacle" term (first studied by Elliott and Blowey).

We will describe fast (GPU-optimized) variational solvers for gradient flows of these functionals (Allen-Cahn and Cahn-Hilliard equivalents), and also look into certain higher-dimensional generalisations.
