守恒光流:angular momentum和自旋
Conserving optical currents: angular momentum and spin
摘要:
在麦克斯韦方程组的第一次量子化中,我们引入了电磁场的动能、线动量、角动量和光自旋。我们表明,这些不同的数量是保守的光在真空中的传播过程中,是添加剂只为本征模的电磁场。
英文摘要:
Within the first quantisation of Maxwell's equations, we introduce the dynamic energy, linear momentum, angular momentum and optical spin of the electromagnetic fields. We show that these different quantities are conserved during the propagation of light in vacuum and are additive only for eigenmodes of the electromagnetic field.
