Understanding the electromagnetic 4-potential in the tetrad bundle [PDF]
Phys.Rev.A.98,033809 (2018), 2018 Separation of the spin and orbital angular momenta of the electromagnetic field has been discussed frequently in recent years. The spin and orbital angular momenta cannot be made simultaneously gauge invariant and Lorentz covariant and are not conserved separately.

The Structure of an Electromagnetic Field [PDF]
Proceedings of the National Academy of Sciences, 1918 This elementary field corresponds to a state of affairs in which electric charges of a concentrated form are created and travel along straight lines with the velocity of light, the directions of these lines being specified by the different values of the unit vector s.

Fractional Electromagnetic Field Theory and Its Applications [PDF]
arXiv, 2022 Fractional electromagnetic field theory describes electromagnetic wave propagation through the complex, nonlocal, dissipative, fractal and also recent artificially engineered materials know as fractional metamaterials. In this theory using the fractional Maxwell equations we are also able to consider the well-known effect of electromagnetic memory.

Photon creation in a spherical oscillating cavity [PDF]
, 2006 We study the photon creation inside a perfectly conducting, spherical oscillating cavity. The electromagnetic field inside the cavity is described by means of two scalar fields which satisfy Dirichlet and (generalized) Neumann boundary conditions.

Contribution of electric self-forces to electromagnetic momentum in a moving system [PDF]
arXiv, 2022 In moving electromagnetic systems, electromagnetic momentum calculated from the vector potential is shown to be proportional to the field energy of the system. The momentum thus obtained is shown actually to be the same as derived from a Lorentz transformation of the rest-frame electromagnetic energy of the system, assuming electromagnetic energy ...

The $ννγ$ Amplitude in an External Homogeneous Electromagnetic Field [PDF]
Phys.Rev. D62 (2000) 113005, 2000 Neutrino-photon interactions in the presence of an external homogeneous constant electromagnetic field are studied. The $\nu \nu \gamma $ amplitude is calculated in an electromagnetic field of the general type, when the two field invariants are nonzero.
