We discuss the influence of dissipation at a system boundary (film-meniscus interface) on the dynamics of dislocation loops inside a smectic film. This dissipation induces a strong coupling between dislocations-effectively independent of their separation-leading to their nontrivial dynamics. Because of these dynamics, the effective "dynamical" radius of nucleation can be 10 times larger than the usual static critical radius.
我们讨论了系统边界(薄膜-弯月面界面)处的耗散对近晶薄膜内位错环动力学的影响。这种耗散在有效上与位错间距无关的情况下,在位错之间诱导出强耦合,从而导致它们呈现出非平凡的动力学。由于这些动力学,成核的有效“动力学”半径可比通常的静态临界半径大10倍。
