驱动三维伊辛界面:波动、魔鬼阶梯和界面几何效应

Driven 3D Ising Interface: its fluctuation, Devil's staircase, and effect of interface geometry

Manish K. Sahai

摘要:

界面上存在着迷人的波纹图案,并在其起伏轮廓中表现出来。在矩形三维伊辛系统上,这些波纹是在非均匀外场作用下,界面发生波动时产生的。脉动结构和流动具有时间周期性,最终具有一定的调制性,并具有场界面的几何特征。剧烈的转变发生在波动轮廓作为动力学和力场界面的几何形状的函数,并被分为两个空间区域:波纹和平滑。对于我们所关心的速度,接口与场接口固定,并且对于场剖面的任意方向,接口的波纹部分的局部斜率被锁定到最接近剖面的几个合理值(魔鬼阶梯)的组合中,从而生成镜面图案的补丁。

英文摘要:

Enchanting ripple pattern exist on interface, and manifest them self in it's fluctuation profile as well. These ripples apparently flow as the interface struck with inhomogeneous externally driven field interface, moves fluctuating about it on a rectangular 3D Ising system. Ripple structure and flow have temporal periodicity, eventually with some modulation, and have signature of geometry of field interface. Dramatic transitions occur in fluctuation profile as a function of dynamics and geometry of the force field interface and is divided into two spatial regions : rippled and smooth. For the velocity we are concerned with, the interface is pinned with field interface, and for arbitrary orientations of the field profile local slope of the rippled part of the interface gets locked in to a combination of few rational values (Devil's staircase) which most closely approximate the profile, thereby generating specular pattern of patches.
