Topology, nonlocality and duality in classical electrodynamics
José A. Heras, Ricardo Heras
We have recently (Heras et al. in Eur. Phys. J. Plus 136:847, 2021) argued that classical electrodynamics can predict nonlocal effects by showing an example of a topological and no…
Can classical electrodynamics predict nonlocal effects?
José A. Heras, Ricardo Heras
Classical electrodynamics is a local theory describing local interactions between charges and electromagnetic fields and therefore one would not expect that this theory could predi…
Helmholtz's theorem for two retarded fields and its application to Maxwell's equations
José A. Heras, Ricardo Heras
An extension of the Helmholtz theorem is proved, which states that two retarded vector fields and satisfying appropriate initial and boundary conditions are…
The classical counterpart of the Aharonov-Bohm phase
Ricardo Heras
The existence of the Aharonov-Bohm phase shows that the magnetic field may produce nonlocal effects in quantum mechanics. It is generally believed that such a nonlocal behavior of…
The Helmholtz theorem and retarded fields
Ricardo Heras
Textbooks frequently use the Helmholtz theorem to derive expressions for the electrostatic and magnetostatic fields but they do not usually apply this theorem to derive expressions…
Initial accelerations of pulsars caused by external kicks
Ricardo Heras
Using energy conservation we show that if a sudden external force of unknown nature causes a newborn pulsar of mass and radius R=10 km to have the acceleration $a_0…
