世界线形式中具有Robin边界条件的标量场

Scalar Field with Robin Boundary Conditions in the Worldline Formalism

Fiorenzo Bastianelli, Olindo Corradini, Pablo A. G. Pisani

摘要:

在量子场论中,世界线形式被广泛用于计算物理量。然而,这种形式主义的应用,量子领域中存在的边界已被研究最近。在这篇文章中,我们展示了如何计算在世界线方法的标量场的罗宾型边界条件的热核展开。为了描述这一机制的工作原理,我们计算了边界条件对正实数线上标量场热核展开系数A_1、A_{3/2}和A_2的贡献。

英文摘要:

The worldline formalism has been widely used to compute physical quantities in quantum field theory. However, applications of this formalism to quantum fields in the presence of boundaries have been studied only recently. In this article we show how to compute in the worldline approach the heat kernel expansion for a scalar field with boundary conditions of Robin type. In order to describe how this mechanism works, we compute the contributions due to the boundary conditions to the coefficients A_1, A_{3/2} and A_2 of the heat kernel expansion of a scalar field on the positive real line.
