论文摘要
我们表明，具有表面松弛的通用动力学生长过程可以在尺寸$ d <4 $的情况下显示出新的皱巴巴相位，并具有短距离定向顺序。与粒子电流相关的化学电位的足够强的空间非本地部分可以触发这种折磨。该系统还可以处于具有远距离定向顺序的触觉上可访问的粗糙阶段，但$ d <4 $的短范围位置顺序和已知的缩放指数。有趣的是，在$ d> 4 $中，我们认为没有皱巴巴的过渡。取而代之的是，对于足够大的非本地粒子电流，从光滑到粗糙相的粗糙过渡。讨论了这些结果的实验和理论意义。
We show that generic kinetic growth processes with surface relaxations can exhibit a new crumpled phase with short-range orientational order at dimensions $d<4$. A sufficiently strong spatially non-local part of the chemical potential associated with the particle current above a threshold in the system can trigger this crumpling. The system can also be in a perturbatively accessible rough phase with long range orientational order but short range positional order at $d<4$ with known scaling exponents. Intriguingly, in $d>4$ we argue that there is no crumpling transition; instead, there is a roughening transition from a smooth to a rough phase for large enough non-local particle current. Experimental and theoretical implications of these results are discussed.
