一维库仑势的路径积分的精确性

Exactness in the Path Integral of the Coulomb Potential in One Space Dimension

Seiji Sakoda

摘要:

本文精确求解了一维库仑系统的时间分片路径积分。在制定路径积分,我们使用的Duru-Kleinert变换与Fujikawa的规范理论技术。费曼核的动量表示的束缚态和散射态将得到明确的极点结构,解释了准确的路径积分。因此,本文给出的路径积分可以利用柯西积分定理精确地计算。

英文摘要:

We solve time-sliced path integrals of one-dimensional Coulomb system in an exact manner. In formulating path integrals, we make use of the Duru-Kleinert transformation with Fujikawa's gauge theoretical technique. Feynman kernels in the momentum representation both for bound states and scattering states will be obtained with clear pole structure that explains the exactness of the path integral. The path integrals presented here can be, therefore, evaluated exactly by making use of Cauchy's integral theorem.
