论文摘要
我们提出了由Plebanski-Type Lagrangians描述的非线性电动力学中的光模式的3+1公式，其中包括后马克斯威尔后，出生于In-Infeld，Modmax和Heisenberg-euler-euler-schwinger-Schwinger Qed Lagrangians。在非线性电动力学中，强电磁场将真空修改以获取光学特性。这种现场修饰的真空吸尘器可以具有电介电常数，磁渗透性和磁电响应，从而引起新的现象，例如真空双折射。通过利用Plebanski型拉格朗日的数学结构，我们获得了简化的程序和明确的公式，以确定给定传播方向的光模式，即折射率和极化向量。我们还为任意强的磁场来解决上述拉格朗日人的光模式。本文提出的3+1配方直接应用于当前的真空双折射研究：使用永久磁铁/超易于强激光器的陆生实验，用于对近临界和超级策略和超级策略制度的X射线的亚临界状态和天体物理观察。
We present a 3+1 formulation of the light modes in nonlinear electrodynamics described by Plebanski-type Lagrangians, which include Post-Maxwellian, Born-Infeld, ModMax, and Heisenberg-Euler-Schwinger QED Lagrangians. In nonlinear electrodynamics, strong electromagnetic fields modify the vacuum to acquire optical properties. Such a field-modified vacuum can possess electric permittivity, magnetic permeability, and magneto-electric response, inducing novel phenomena like vacuum birefringence. By exploiting the mathematical structures of Plebanski-type Lagrangians, we obtain a streamlined procedure and explicit formulas to determine light modes, i.e., refractive indices and polarization vectors for a given propagation direction. We also work out the light modes of the mentioned Lagrangians for an arbitrarily strong magnetic field. The 3+1 formulation advanced in this paper has direct applications to the current vacuum birefringence research: terrestrial experiments using permanent magnets/ultra-intense lasers for the subcritical regime and astrophysical observation of the x-rays from highly magnetized neutron stars for the near-critical and supercritical regimes.
