均匀钉扎模型的有限尺度标度

Finite size scaling for homogeneous pinning models

Julien Sohier

摘要:

钉扎模型是从离散更新序列通过奖励(或惩罚)的轨迹,根据他们的更新时期的数量到时间$N$,和$N$,然后发送到无穷大。它们是统计力学模型,受到了很多关注,因为它们与应用非常相关,并且因为它们的{ \sl精确可解特性},同时显示非平凡相变(事实上,局部化转变)。跃迁的顺序取决于底层更新的到达间隔律的尾部,当这样的尾部足够重时,跃迁是连续的:这是我们将关注的情况。本文的主要目的是对钉扎模型的{ \sl有限尺寸标度极限}进行数学处理,即研究当系统尺寸与关联长度成正比时,过程接近临界的极限(按定律)。

英文摘要:

Pinning models are built from discrete renewal sequences by rewarding (or penalizing) the trajectories according to their number of renewal epochs up to time $N$, and $N$ is then sent to infinity. They are statistical mechanics models to which a lot of attention has been paid both because they are very relevant for applications and because of their {\sl exactly solvable character}, while displaying a non-trivial phase transition (in fact, a localization transition). The order of the transition depends on the tail of the inter-arrival law of the underlying renewal and the transition is continuous when such a tail is sufficiently heavy: this is the case on which we will focus. The main purpose of this work is to give a mathematical treatment of the {\sl finite size scaling limit} of pinning models, namely studying the limit (in law) of the process close to criticality when the system size is proportional to the correlation length.
