关于狄拉克方程的推导

On the derivation of the Dirac Equation

R. Sartor

摘要:

我们指出,狄拉克矩阵的反对易性可以推导出没有平方狄拉克哈密顿量,也就是说,没有明确的参考克莱因-戈登方程。我们只要求狄拉克方程允许两个线性无关的平面波解,且对所有动量具有正能量。负能量的必要性以及狄拉克矩阵的迹和行列式性质也是这个简单和最小要求的直接结果。

英文摘要:

We point out that the anticommutation properties of the Dirac matrices can be derived without squaring the Dirac hamiltonian, that is, without explicit reference to the Klein-Gordon equation. We only require the Dirac equation to admit two linearly independent plane wave solutions with positive energy for all momenta. The necessity of negative energies as well as the trace and determinant properties of the Dirac matrices are also a direct consequence of this simple and minimal requirement.
