Role of the non-locality of the vector potential in the Aharonov-Bohm effect
A. M. Stewart
When the electromagnetic potentials are expressed in the Coulomb gauge in terms of the electric and magnetic fields rather than the sources responsible for these fields they have a…
Quantization of the free electromagnetic field implies quantization of its angular momentum
A. M. Stewart
It is shown that when the gauge-invariant Bohr-Rosenfeld commutators of the free electromagnetic field are applied to the expressions for the linear and angular momentum of the ele…
Comparison of different forms for the "spin" and "orbital" components of the angular momentum of light
A. M. Stewart
We compare three attempts that have been made to decompose the angular momentum of the electromagnetic field into components of an "orbital" and "spin" nature. All three expression…
On an identity for the volume integral of the square of a vector field
A. M. Stewart
A proof is given of the vector identity proposed by Gubarev, Stodolsky and Zakarov that relates the volume integral of the square of a 3-vector field to non-local integrals of the…
Derivation of the paraxial form of the angular momentum of the electromagnetic field from the general form
A. M. Stewart
It is shown how the standard forms for the spin and orbital components of the angular momentum of a paraxial wave of electromagnetic radiation are obtained from the general express…
Equivalence of two mathematical forms for the bound angular momentum of the electromagnetic field
A. M. Stewart
It is shown that the mathematical form, obtained in a recent paper, for the angular momentum of the electromagnetic field in the vicinity of electric charge is equivalent to anothe…
