The massive side of the electromagnetic waves
arXiv:2308.12860 · doi:10.1016/j.aop.2023.169454
Abstract
Stationary electromagnetic waves display aspects that are shared with massive particles, since the energy and momentum contained in a volume of sides equal to the wavelengths form a non-zero energy-momentum invariant. The parallel can be extended to the notion of weight when this concept makes sense, that is, in the Newtonian chart of a weak inertial-gravitational field.
