Photon and lorentz covariance pdf
WebLorentz covariance of momentum-energy four-vector. The momentum of light in a medium can be described by a single photon’s momentum or by EM momentum. As we know, the phase function for a plane wave characterizes the propagation of energy and momentum of light. Because the phase function is a Lorentz invariant and it is symmetric with WebWave four-vector in a moving medium and the Lorentz covariance of Minkowski’s photon and electromagnetic momentums . Changbiao Wang ShangGang Group, 70 Huntington Road, Apartment 11, New Haven, CT 06512, USA In this paper, by analysis of a plane wave in a moving dielectric medium, it is shown that the invariance of phase is a natural result …
