一维散射的J矩阵方法:相对论理论

J-matrix method of scattering in one dimension: The relativistic theory

A. D. Alhaidari

摘要:

本文对一维J矩阵散射方法作了相对论性推广。相对论势矩阵是矢量、标量和赝标量分量的组合。这些都是非奇异的短程势函数(不一定是解析的),使得它们在支持自由狄拉克算子的三对角对称矩阵表示的平方可积基集的有限子集中由它们的矩阵元素很好地表示。透射和反射系数计算不同的潜在的耦合模式。这是两篇论文序列中的第一篇,我们在这一部分中发展理论,然后在第二部分中应用。

英文摘要:

We make a relativistic extension of the one-dimensional J-matrix method of scattering. The relativistic potential matrix is a combination of vector, scalar, and pseudo-scalar components. These are non-singular short-range potential functions (not necessarily analytic) such that they are well represented by their matrix elements in a finite subset of a square integrable basis set that supports a tridiagonal symmetric matrix representation for the free Dirac operator. Transmission and reflection coefficients are calculated for different potential coupling modes. This is the first of a two-paper sequence where we develop the theory in this part then follow it with applications in the second.
