II之外的action中含$ϕ^4$项泛函积分

Functional integral with $ϕ^4$ term in the action beyond standard perturbative methods II

Juraj Boháčik, Peter Prešnajder

摘要:

为了避免无穷测度问题,谐振子的泛函积分可以用Gelfand和Yaglom提出的连续极限方法的时间切片方法计算。在前一篇文章中,我们用非微扰计算证明了具有正、负质量项的非谐振子的广义Gelfand-Yaglom方程。本文逐步证明了非谐振子Gelfand-Yaglom方程修正函数的计算。

英文摘要:

To avoid problems with infinite measure, the functional integral for harmonic oscillator can be calculated by time - slicing method with continuum limit procedure proposed Gelfand and Yaglom. In previous article we proved by nonperturbative calculation the generalized Gelfand-Yaglom equation for anharmonic oscillator with positive or negative mass term. In this article we prove by step-by-step the calculation of the correction function to the Gelfand-Yaglom equation for an-harmonic oscillator.
