论文摘要
我们研究了在整个关键区域突然淬灭之后，由紧凑型Kardar-Parisi-Zhang方程描述的二维非平衡系统中的涡流动力学。我们对相位序动力学的确切数值解决方案表明，非平衡性与空间各向异性的可变程度之间的独特相互作用会导致不同的关键状态。我们基于缩放参数提供了涡流演化的分析表达，该参数与数值结果一致，并确认了该系统中涡流之间的相互作用势的形式。
We study the dynamics of vortices in a two-dimensional, non-equilibrium system, described by the compact Kardar-Parisi-Zhang equation, after a sudden quench across the critical region. Our exact numerical solution of the phase-ordering kinetics shows that the unique interplay between non-equilibrium and the variable degree of spatial anisotropy leads to different critical regimes. We provide an analytical expression for the vortex evolution, based on scaling arguments, which is in agreement with the numerical results, and confirms the form of the interaction potential between vortices in this system.
