论文摘要
接口的粗糙性意味着接口宽度$ W $与系统尺寸$ L $的差异。对于二维系统，$ w^2 $的差异为$ l $。在详细的毛细管波近似和统计场理论的框架中，我们得出了$ W^2 $的渐近行为的表达，这与文献的结果不同。蒙特卡洛模拟证实了这一点。
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.
