Growth of Order in An Anisotropic Swift-Hohenberg Model
Hai Qian, Gene F. Mazenko
We have studied the ordering kinetics of a two-dimensional anisotropic Swift-Hohenberg (SH) model numerically. The defect structure for this model is simpler than for the isotropic…
The Vortex Kinetics of Conserved and Non-conserved O(n) Models
Hai Qian, Gene F. Mazenko
We study the motion of vortices in the conserved and non-conserved phase-ordering models. We give an analytical method for computing the speed and position distribution functions f…
A Model for Striped Growth
Hai Qian, Gene F. Mazenko
We introduce a model for describing the defected growth of striped patterns. This model, while roughly related to the Swift-Hohenberg model, generates a quite different mixture of…
Vortex Dynamics in a Coarsening Two Dimensional XY Model
Hai Qian, Gene F. Mazenko
The vortex velocity distribution function for a 2-dimensional coarsening non-conserved O(2) time-dependent Ginzburg-Landau model is determined numerically and compared to theoretic…
Defect Structures in the Growth Kinetics of the Swift-Hohenberg Model
Hai Qian, Gene F. Mazenko
The growth of striped order resulting from a quench of the two-dimensional Swift-Hohenberg model is studied in the regime of a small control parameter and quenches to zero temperat…
