Within the framework of a derivable construction of QED, a formulation of nonlinear axion-electrodynamics is investigated. This approach is intended to predict possible strong-QED processes with a discussion of the role of axion-like particles that might be significant in nonlinear electrodynamics (NLED). We introduce a nonlinear model of axion-electrodynamics with remaining questions to be further explored.

非线性轴子电动力学模型

在 QED 的可推导结构的框架内，研究了非线性轴子电动力学的公式。这种方法旨在通过讨论可能在非线性电动力学 (NLED) 中具有重要意义的类轴子粒子的作用来预测可能的强 QED 过程。我们介绍了一个轴子电动力学的非线性模型，剩下的问题有待进一步探索。
