A theory of electromagnetism with uniquely defined potential and covariant conserved spin
AI总结：
本文基于费米拉格朗日量提出一种电磁理论，通过非齐次波动方程唯一确定四维势，并证明电磁自旋守恒、量子化完全协变，同时所有实验预测与标准理论一致，从而说明电磁规范不变性作为基本原理是多余的。
摘要：
本文提出一种基于费米拉格朗日量的电磁理论，该拉格朗日量在电磁自旋旋转下具有对称性。其特点如下：四维势由非齐次波动方程和无穷远处边界条件唯一确定；洛伦兹条件与最小耦合随后由电荷守恒导出；电磁自旋守恒，并且可以在不牺牲协变性的情况下定义自旋算符；量子化完全协变，无需重新定义度规；所有实验预测与标准理论相同。这一结果证明，作为物理学基本原理，电磁规范不变性是多余的。
英文摘要：
A theory of electromagnetism is proposed that is based on the Fermi Lagrangian, which is symmetric under electromagnetic spin rotation. Its features are: - the four-potential is unambiguously determined by the inhomogeneous wave equation and boundary conditions at infinity. - the Lorenz condition and minimal coupling then follow from charge conservation. - electromagnetic spin is conserved and spin operators can be defined without sacrificing covariance. - quantisation is fully covariant, without redefining the metric. - all experimental predictions are the same as in the standard theory. This result proves that electromagnetic gauge invariance is redundant as a fundamental principle of physics.
