二维界面生长:Loewner方程方法

Interface growth in two dimensions: A Loewner-equation approach

Miguel A. Durán, Giovani L. Vasconcelos

摘要:

在Loewner方程的框架内,在二维拉普拉斯增长的问题被认为是。本文首先讨论了Gubiec和Szymczak [T. Gubiec和P.Szymczak,Phys.Rev.E77,041602(2008)],并且报道了三指配置的新的精确解。然后引入了一类一般的界面在上半平面内生长的生长模型,并导出了相应的Loewner方程。给出了几个示例,包括具有一个或多个尖端的接口以及多个生长接口。我们的接口增长模型的“Loewner域”,其中的增长规则是由一个时间演变的措施,概括进行了简要的讨论。

英文摘要:

The problem of Laplacian growth in two dimensions is considered within the Loewner-equation framework. Initially the problem of fingered growth recently discussed by Gubiec and Szymczak [T. Gubiec and P. Szymczak, Phys. Rev. E 77, 041602 (2008)] is revisited and a new exact solution for a three-finger configuration is reported. Then a general class of growth models for an interface growing in the upper-half plane is introduced and the corresponding Loewner equation for the problem is derived. Several examples are given including interfaces with one or more tips as well as multiple growing interfaces. A generalization of our interface growth model in terms of ``Loewner domains,'' where the growth rule is specified by a time evolving measure, is briefly discussed.
