二维自旋冰模式中的非平衡动力学

Out of equilibrium dynamics in the bidimensional spin-ice model

Demian Levis, Leticia F. Cugliandolo

摘要:

我们研究了2d自旋冰从完全无序的初始条件(无限温度下的平衡)猝灭到无序、铁磁和反铁磁相后的动力学。我们分析的拓扑缺陷的密度的演变,我们表明,这些需要有限的密度在很长一段时间内,在各种淬火。我们确定了领先的机制有序相的增长领域,我们评估(各向异性)增长的长度参与动态缩放。

英文摘要:

We study the dynamics of 2d spin-ice following a quench from a fully disordered initial condition (equilibrium at infinite temperature) into its disordered, ferromagnetic and antiferromagnetic phases. We analyze the evolution of the density of topological defects and we show that these take finite density over very long periods of time in all kinds of quenches. We identify the leading mechanisms for the growth of domains in the ordered phases and we evaluate the (anisotropically) growing lengths involved in dynamic scaling.
