Polarizabilities of microparticles in relativistic field theory
摘要：
本文从麦克斯韦方程组出发，通过确定结构微粒的电荷密度和极化电流，确定了包含介质的电、磁极化矢量的二阶相对论张量。利用该张量和电磁场张量，考虑结构元素的极化，得到了电磁场与结构微粒相互作用的相对论拉格朗日量。基于诱导矩，考虑电磁极化率，构造了电磁场与结构微粒相互作用的相对论拉格朗日量。
英文摘要：
The article determine a relativistic tensor of the second rank containing the vectors of the electric and magnetic polarization of the medium, based on the Maxwell equations and the determination of the charge density and polarization current of a structural microparticle. Using this tensor and the electromagnetic field tensor, the relativistic lagrangian of the interaction an electromagnetic field with a structural microparticle is obtained, taking into account the polarization of its structural elements. Based on the induced moments, the relativistic lagrangian of the interaction an electromagnetic field with a structural microparticle is constructed with considering the electric and magnetic polarizabilities.
