摘要:

我们提出了一种计算量子场论中单圈有效作用量和真空能的方法。谱函数是由算符本征值定义的函数。量子场论中的单圈有效作用量与真空能,以及量子力学中的散射相移和散射振幅,均属于谱函数。若能确定不同谱函数之间的变换关系,就可通过该变换从一个谱函数得到另一个。本文将计算散射相移和散射振幅的量子力学方法,转化为计算单圈有效作用量和真空能的量子场论方法。

英文摘要:

We propose an approach for calculating one-loop effective actions and vacuum energies in quantum field theory. Spectral functions are functions defined by the eigenvalues of an operator. One-loop effective actions and vacuum energies in quantum field theory, as well as scattering phase shifts and scattering amplitudes in quantum mechanics, are all spectral functions. If a transformation between different spectral functions is identified, we can obtain a spectral function from another through the transformation. In this paper, we convert quantum mechanical methods for calculating scattering phase shifts and scattering amplitudes into quantum field theory methods for calculating one-loop effective actions and vacuum energies.
