用围道积分计算行列式

Computation of determinants using contour integrals

Klaus Kirsten, Paul Loya

摘要:

它示出了如何使用轮廓积分的费曼传播的一大类潜在的指数因子可以计算。这与量子理论中的隧穿过程有直接关系。这种分析的先决条件是访问先进的本科生,只涉及在常微分方程和复变量的入门课程。

英文摘要:

It is shown how the pre-exponential factor of the Feynman propagator for a large class of potentials can be computed using contour integrals. This is of direct relevance in the context of tunnelling processes in quantum theories. The prerequisites for this analysis are accessible to advanced undergraduate students and involve only introductory courses in ordinary differential equations and complex variables.
