二维界面粗糙化

Interface roughening in two dimensions

Gernot Münster, Manuel Cañizares Guerrero

摘要:

界面粗糙化意味着界面宽度$w$与系统尺寸$L$的差异。对于二维系统,$w^2$的发散在$L$中是线性的。在一个详细的毛细波近似和统计场论的框架下,我们推导出一个表达式的渐近行为的$w^2$,这不同于文献中的结果。通过蒙特卡罗模拟证实了这一点。

英文摘要:

Roughening of interfaces implies the divergence of the interface width $w$ with the system size $L$. For two-dimensional systems the divergence of $w^2$ is linear in $L$. In the framework of a detailed capillary wave approximation and of statistical field theory we derive an expression for the asymptotic behaviour of $w^2$, which differs from results in the literature. It is confirmed by Monte Carlo simulations.
