高阶相互作用的环顶点展开

Loop Vertex Expansion for Higher Order Interactions

Vincent Rivasseau

摘要:

本说明提供了构造性循环顶点扩展到任意高阶稳定相互作用的扩展,为许多应用开辟了道路。我们详细处理的例子$(\bar ϕϕ)^p$场论在零维。我们发现,重要的功能,以延长循环顶点扩展是不使用中间字段表示,而是强制集成的初始行动的每个顶点的一个特定的字段。

英文摘要:

This note provides an extension of the constructive loop vertex expansion to stable interactions of arbitrarily high order, opening the way to many applications. We treat in detail the example of the $(\bar ϕϕ)^p$ field theory in zero dimension. We find that the important feature to extend the loop vertex expansion is not to use an intermediate field representation, but rather to force integration of exactly one particular field per vertex of the initial action.
