论文摘要
当将空间局部应力应用于生长的一维界面时,界面会变形。该变形通过代表界面刚度的有效表面张力来描述。我们表明,刚度在大型系统尺寸限制中表现出不同的行为,即与热噪声增长的界面,这对于平衡接口从未观察到。此外,通过将有效的表面张力与时空相关函数联系起来,我们阐明了异常动力学波动会导致刚度不同的机制。
When a spatially localized stress is applied to a growing one-dimensional interface, the interface deforms. This deformation is described by the effective surface tension representing the stiffness of the interface. We present that the stiffness exhibits divergent behavior in the large system size limit for a growing interface with thermal noise, which has never been observed for equilibrium interfaces. Furthermore, by connecting the effective surface tension with a space-time correlation function, we elucidate the mechanism that anomalous dynamical fluctuations lead to divergent stiffness.
