Maxwell Electrodynamics in Terms of Physical Potentials

  title={Maxwell Electrodynamics in Terms of Physical Potentials},
  author={Parthasarathi Majumdar and Anarya Ray},
A fully relativistically covariant and manifestly gauge-invariant formulation of classical Maxwell electrodynamics is presented, purely in terms of gauge-invariant potentials without entailing any gauge fixing. We show that the inhomogeneous equations satisfied by the physical scalar and vector potentials (originally discovered by Maxwell) have the same symmetry as the isometry of Minkowski spacetime, thereby reproducing Einstein’s incipient approach leading to his discovery of special…

The Relativistic Point Charge Revisited : Novel Features

A fully relativistically covariant formulation of the classical Maxwell electrodynamics of an arbitrarily-moving point charge is presented, purely in terms of gauge invariant potentials without

A Non-Local Action for Electrodynamics: Duality Symmetry and the Aharonov-Bohm Effect, Revisited

It is shown how the electric-magnetic duality symmetry of the electromagnetic field and the Aharonov–Bohm effect can be derived from the simple harmonic oscillator character of vacuum electrodynamics, while also demonstrating how the magnetic version of the latter naturally arises in an explicitly non-local manner.

Implications of Gauge-Free Extended Electrodynamics

Preliminary experiments have validated the SLW’s no-skin-effect constraint as a potential harbinger of new technologies, a possible explanation for poorly understood laboratory and astrophysical phenomena, and a forerunner of paradigm revolutions.

Probing the post-Minkowskian approximation using recursive addition of self-interactions

We address the problem of deriving the post-Minkowskian approximation, widely used in current gravitational wave literature by investigating a possible deduction out of the recursive Nother coupling

Symmetry in Electromagnetism

Electromagnetism plays an essential role, both in basic and applied physics research and in medicine, and has an important role in medicine and drug discovery.



Point-particles and energy tensors in special relativity

SummaryIn order to study the interactions of point-particles in terms of classical concepts, it is necessary to calculate the flux of 4-momentum across a tube enclosing the world line of a particle.

Gauge-invariant matter field actions from an iterative Noether coupling

Generalizing Deser's work on pure $SU(2)$ gauge theory, we consider scalar, spinor and vector matter fields transforming under arbitrary representations of a non-Abelian, compact, semisimple internal

Significance of Electromagnetic Potentials in the Quantum Theory

In this paper, we discuss some interesting properties of the electromagnetic potentials in the quantum domain. We shall show that, contrary to the conclusions of classical mechanics, there exist

The conceptual origins of Maxwell’s equations and gauge theory

Already in Faraday’s electrotonic state and Maxwell’s vector potential, gauge freedom was an unavoidable presence. Converting that presence to the symmetry principle that underpins our successful

Quantum field theory is the framework in which the regnant theories of the electroweak and strong interactions, which together form the standard model, are formulated. Quantum electrodynamics (QED),

Model universes with spherical symmetry

SummarySpherically symmetric universes are defined, and spherically symmetric solutions of Einstein's field equations in vacuo are explored in terms of suitable coordinates. The Kruskal metric is
