“…In particular, they keeps on the difference between the linear and nonlinear 3 ˆ dispersion of the media, and the influence of the magnetic permeability 0 . After a special complex transformation of the amplitude functions of NMEs right way we obtain nonlinear Dirac equations with nonlinear terms in first Pauli spinor of the Dirac field only [11,12]. This asymmetry is due of certain physical principlesin arbitrary media, including the nonlinear vacuum, the polarization of the media dominate with 5-6 order of magnitudes than magnetization.…”
