论文摘要
我们考虑电气和磁充电源与麦克斯韦理论的最大对称非线性扩展的耦合，称为modmax。目的是揭示将Modmax与Maxwell的电动力学区分开的物理效应。我们发现，与非线性电动力学的通用模型相比，由移动的电或磁性粒子引起的Lienard-Wiechert场，或者是Modmax运动方程的精确解。然后，我们研究了Modmax非线性是否影响带电物体的电磁相互作用的性质，尤其是Lorentz力，库仑法，Lienard-Wiechert领域，Dirac和Schwinger的电气和磁性电荷的量化以及Compton效应。在传递的过程中，我们还提供了Modmax Lagrangian的另一种形式，就麦克斯韦理论与轴突二元式辅助标量场的耦合而言，这可能与揭示Modmax的有效场理论起源有关。
We consider couplings of electrically and magnetically charged sources to the maximally symmetric non-linear extension of Maxwell's theory called ModMax. The aim is to reveal physical effects which distinguish ModMax from Maxwell's electrodynamics. We find that, in contrast to generic models of non-linear electrodynamics, Lienard-Wiechert fields induced by a moving electric or magnetic particle, or a dyon are exact solutions of the ModMax equations of motion. We then study whether and how ModMax non-linearity affects properties of electromagnetic interactions of charged objects, in particular the Lorentz force, the Coulomb law, the Lienard-Wiechert fields, Dirac's and Schwinger's quantization of electric and magnetic charges, and the Compton Effect. In passing we also present an alternative form of the ModMax Lagrangian in terms of the coupling of Maxwell's theory to axion-dilaton-like auxiliary scalar fields which may be relevant for revealing the effective field theory origin of ModMax.
