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…
Domain Wall Renormalization Group Study of XY Model with Quenched Random Phase Shifts
N. Akino, J. M. Kosterlitz
The XY model with quenched random disorder is studied by a zero temperature domain wall renormalization group method in 2D and 3D. Instead of the usual phase representation we use…
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…
Numerical Study of Order in a Gauge Glass Model
J. M. Kosterlitz, N. Akino
The XY model with quenched random phase shifts is studied by a T=0 finite size defect energy scaling method in 2d and 3d. The defect energy is defined by a change in the boundary c…
Numerical Study of Spin and Chiral Order in a Two-Dimensional XY Spin Glass
J. M. Kosterlitz, N. Akino
The two dimensional XY spin glass is studied numerically by a finite size scaling method at T=0 in the vortex representation which allows us to compute the exact (in principle) spi…
