...Approximately 50 years ago, Ginzburg and Landau [16] formulated a model for superconductivity using a complex valued order parameter and its gradients, and Cahn and Hilliard [17] proposed a thermodynamic formulation that accounts for the gradients in thermodynamic properties in heterogeneous systems with diffuse interfaces....
