随机矩阵理论的一种新方法

Replica Approach in Random Matrix Theory

Eugene Kanzieper

摘要:

本章概述了随机矩阵理论中的复制方法。费米子和玻色子版本的副本限制的介绍和它的诡计进行了讨论。简要概述了早期的启发式处理的零维副本场论主张一个精确的方法来复制品。后者提出了两个阐述:通过查看的$β=2$副本配分函数户田格和嵌入副本配分函数到一个更一般的理论$τ$功能。

英文摘要:

This Chapter outlines the replica approach in Random Matrix Theory. Both fermionic and bosonic versions of the replica limit are introduced and its trickery is discussed. A brief overview of early heuristic treatments of zero-dimensional replica field theories is given to advocate an exact approach to replicas. The latter is presented in two elaborations: by viewing the $β=2$ replica partition function as the Toda Lattice and by embedding the replica partition function into a more general theory of $τ$ functions.
