We study the role played by topological textures and antitextures during the phase ordering of a two-dimensional system described by the discretised nonlinear O(3) sigma model with purely dissipative dynamics. We identify and characterise two distinct mechanisms for the decay of the order parameter variations --- single texture unwinding, and topological charge annihilation. Our results show that while at early times after the quench, the annihilation process dominates, the unwinding processes…

In Chap. 2, we introduced kinetic Ising models and the corresponding coarse-grained models for order-parameter kinetics. We also discussed the utility of these models in the context of phase ordering…

This work investigated the annihilation dynamics of defects and antidefects in a lyotropic nematic liquid crystal using the polarized optical light microscopy technique and obtained for the distance D between two annihilating defects, as a function of time t remaining for the annihilation, the scaling law D ∝ t(α).
