在本文中,我们研究了通过粒子的随机分解在一维基底上逐层生长的两个晶体之间碰撞所产生的界面。我们将该接口与等效定向聚合物模型中的 β 路径概念联系起来,并通过使用 J. Baik 和 E. Rains、J. Stat 的渐近结果。物理学,100:523–541(2000)。以及 E. Cator 和 P. Groeneboom, Ann 介绍的一些流体动力学工具。 Probab., 33:879–903 (2005),我们推导出这样一条路径的大数定律,并获得其波动的一些界限。
In this article we study the interface generated by the collision between two crystals growing layer by layer on a one-dimensional substrate through random decomposition of particles. We relate this interface with the notion of β-path in an equivalent directed polymer model and, by using asymptotics results from J. Baik and E. Rains, J. Stat. Phys., 100:523–541 (2000). and some hydrodynamic tools introduced by E. Cator and P. Groeneboom, Ann. Probab., 33:879–903 (2005), we derive a law of large numbers for such a path and obtain some bounds for its fluctuations.
