摘要

我们使用狄拉克/克利福德矩阵提取闵可夫斯基度规的平方根。由此产生的4 × 4算子dS表示平方根,可用于在相对移动的观察者之间变换四个向量。这影响了通常的洛伦兹变换。另外,它作用于狄拉克双旋量。该算子可用作哈密顿算子来写出相对论旋量的运动方程。这就是标准形式的电子狄拉克方程,它表现为一个运动旋量到静止旋量的变换。该方法已在本系列的第1篇文章中介绍。我们相信,这是一种新的方法,可以获得熟悉的结果。

Quantum Equations of Motion and the Geometrical Imperative II: Relativistic
We extract the square root of the Minkowski metric using Dirac/Clifford ma- trices. The resulting 4 × 4 operator dS that represents the square root, can be used to transform four vectors between relatively moving observers. This effects the usual Lorentz transformation. In addition it acts on a Dirac bi-spinor. The operator can be used as a Hamiltonian operator to write an equation of motion for a relativistic spinor. This turns out to be the Dirac equation for electrons in standard form, which appears as a transformation of a moving spinor to the rest frame of the spinor. This approach was introduced in paper I of this series for non relativistic spinor particles. We believe that is is a new approach to familiar results.
