精确重整化群:一种新的阻塞Action的方法

Exact Renormalization Group : A New Method for Blocking the Action

Jean-Michel Caillol

摘要:

本文研究了非正则标量场理论的精确重整化群,其中场与外源以特殊的非线性方式耦合。威尔逊行动和平均有效行动,然后简单地由勒让德变换到一个平凡的二次型。正则和非正则理论之间的精确映射,以及它们之间的流动的关系。液体理论的应用是勾画。

英文摘要:

We consider the exact renormalization group for a non-canonical scalar field theory in which the field is coupled to the external source in a special non linear way. The Wilsonian action and the average effective action are then simply related by a Legendre transformation up to a trivial quadratic form. An exact mapping between canonical and non-canonical theories is obtained as well as the relations between their flows. An application to the theory of liquids is sketched.
