Surface Laplacian of interfacial thermochemical potential: its role in solid-liquid pattern formation

Abstract Steady-state solid-liquid interfaces allow both analytic description as sharp-interface profiles, and numerical simulation via phase-field modeling as stationary diffuse-interface microstructures. Profiles for sharp interfaces reveal their exact shapes and allow identification of the thermo...
