标题： Minimal length corrections to magnetic birefringence in vacuum

摘要： 我们考虑在存在最小长度（$l_p$）的情况下对Kruglov非线性电动力学的修改，通过考虑广义不确定性原理（GUP）的一种特定公式。 最小长度的存在已被多种量子引力候选理论（包括微扰和非微扰理论）所激发。 我们表明，这种最小长度的修改可能导致零点电场强度的动量依赖性边界，针对上述非线性电动力学模型。 我们进一步表明，最小长度的存在会以恒定且均匀强的外部磁场中修改真空双折射的测量值$\Delta n$。 因此，我们建议，存在一种基本起源的摩擦机制，在强磁场中光子偏振的平行方向起作用，作为量化背景的附加效应。 显示英文摘要

摘要： We consider the modification to Kruglov's non-linear electrodynamics in the presence of minimal length ($l_p$), by considering a specific formulation of generalized uncertainty principle (GUP). The presence of minimal length has been motivated by several candidate theories of quantum-gravity (both perturbative and non-perturbative). We show that, such minimal length modifications could lead to momentum dependent bounds on zero-point electric field strength, for the aforementioned non-linear model of electrodynamics. We further show that, the existence of minimal length modifies the measure of vacuum birefringence $\Delta n$ in a constant and uniformly strong, external magnetic field. We therefore suggest, the presence of a frictional mechanism of fundamental origin, acting in the parallel direction of polarization of photons (in the presence of strong magnetic field), as an additional effect of quantized background.
