Quantization in Classical Electrodynamics [PDF]

open access: possiblePhysics Essays, 2002
The theory of a system consisting of two electrically charged particles is deduced using classical electrodynamics. This theory is applied to hydrogen and hydrogen-like atoms.

The New Classical Electrodynamics

Nature, 1953
EXCEPT for a gauge-fixing condition, Dirac's recent theory1–3 corresponds to the natural form of Maxwell–Lorentz electrodynamics for very fine-grained streams of charged corpuscles all with the same constant mass μ and charge e; the velocity field in the stream is supposed to be continuous and differentiable. The ratio μ′/e is written k; here μ′ is the

Poincaré invariance—classical electrodynamics

Journal of Mathematical Physics, 1989
In a previous paper by the authors [J. Math. Phys. 29, 1361 (1988)] it was shown that, following the standard definition, the angular momentum tensor corresponding to the Coulomb field does not exist (due to the long range of the field). In the present paper, for a general classical field theory, nonconventional definitions for the four-momentum and ...

Pair Production in Classical Electrodynamics

Foundations of Physics, 1998
One of the most relevant features of quantum field theory is the phenomenon of pair production, the existence of which, first suggested by Dirac, was not even suspected in the older theories. On the other hand Feynman, in the spirit of his spatiotemporal approach to quantum mechanics, showed how a description of pair production could be given within ...

Classical electrodynamics of spinning particles

Canadian Journal of Physics, 1984
We consider particles with mass, charge, intrinsic magnetic and electric dipole moments, and intrinsic angular momentum in interaction with a classical electromagnetic field. From this action we derive the equations of motion of the position and intrinsic angular momentum of the particle including the radiation reaction, the wave equations of the ...

Gauge Invariance and Classical Electrodynamics

Physical Review, 1953
A Lagrangian for deriving the Maxwell-Lorentz field equations is obtained by starting from a general tensor of the second rank ${\mathcal{G}}_{\ensuremath{\mu}\ensuremath{\nu}}$, which is expressed as the sum of a symmetric and an antisymmetric part ${\mathcal{G}}_{\ensuremath{\mu}\ensuremath{\nu}}=\ensuremath{\lambda}{g}_{\ensuremath{\mu}\ensuremath ...

On the regularization procedure in classical electrodynamics

Journal of Physics A: Mathematical and General, 2003
Summary: We consider the self-action problem in classical electrodynamics. A strict geometrical sense of commonly used renormalization of mass is made. A regularization procedure is proposed which relies on energy-momentum and angular momentum balance equations. We correct the expression for angular momentum tensor obtained by us in a previous paper [J.
