Results from a comprehensive analytical and numerical study of nonequilibrium dynamics in the two-dimensional complex Ginzburg-Landau equation have been presented. In particular, spiral defects have been used to characterize the domain growth law and the evolution morphology. An asymptotic analysis of the single-spiral correlation function shows a sequence of singularities-analogous to those seen for time-dependent Ginzburg-Landau models with O(n) symmetry, where n is even.
给出了二维复金兹堡 - 朗道方程中非平衡动力学的全面分析和数值研究结果。特别地，螺旋缺陷已被用于表征畴生长规律和演化形态。对单螺旋相关函数的渐近分析显示出一系列奇点，类似于具有(O(n))对称性（(n)为偶数）的含时金兹堡 - 朗道模型中所观察到的奇点。
