Pattern Selection in a Phase Field Model for Directional Solidification
R. N. Costa Filho, J. M. Kosterlitz, Enzo Granato
A symmetric phase field model is used to study wavelength selection in two dimensions. We study the problem in a finite system using a two-pronged approach. First we construct an a…

Screened Vortex Lattice Model with Disorder
C. Giardina', N. V. Priezjev, J. M. Kosterlitz
The three dimensional XY model with quenched random disorder and finite screening is studied. We argue that the system scales to model with and the resulting ef…
