梁矩阵与实Pauli矩阵和Dirac矩阵的辛变换

Symplectic transformations of a beam matrix with real Pauli and Dirac matrices

Herbert E. Müller

摘要:

线性粒子光学中的一个基本问题是找到一个辛变换,使(对称)光束矩阵成为一个特殊的对角形式,称为规范形式。这样做的常规方式涉及与射束矩阵相关的矩阵的特征值分解,并且可以应用于1、2或3个粒子自由度的情况。对于2个自由度,最近提出了一种涉及“实狄拉克矩阵”的不同归一化方法。在本文中,实狄拉克矩阵的数学是不同的。给出了另一种归一化方法,并解决了更一般的解耦问题。提供了波束矩阵的3D视觉表示。给出了涉及实泡利矩阵的单自由度问题的归一化方法。

英文摘要:

A basic problem in linear particle optics is to find a symplectic transformation that brings the (symmetric) beam matrix to a special diagonal form, called normal form. The conventional way to do this involves an eigenvalue-decomposition of a matrix related to the beam matrix, and may be applied to the case of 1, 2 or 3 particle degrees of freedom. For 2 degrees of freedom, a different normalization method involving "real Dirac matrices" has recently been proposed. In the present article, the mathematics of real Dirac matrices is presented differently. Another normalization recipe is given, and more general decoupling problems are solved. A 3D visual representation of the beam matrix is provided. The corresponding normalization method for 1 degree of freedom involving "real Pauli matrices" is also given.
