On the photon vector potential
Chemical Physics, 2001Abstract A method of calculating the expression for the single-photon classic vector potential is proposed. The calculation is performed within the model framework of a non-relativistic one-dimensional harmonic oscillator interacting with a quantized electromagnetic field and with the field of a single external photon. The calculated vector potential

Toroidal vector-potential transformer
2017 Eleventh International Conference on Sensing Technology (ICST), 2017We investigated the characteristics of a triple coil comprising a very long, thin, flexible solenoid coil wound around a hollow toroid. In ordinal magnetic-toroidal coils, the current flows in the poloidal direction, generating magnetic field in toroidal direction, but in our vector-potential coil, the magnetic flux flows in the poloidal direction ...

An introduction to the vector potential
European Journal of Physics, 2004The authors discuss the physical means of the vector potential \(A\) in electromagnetism. They consider a long solenoid and the magnetic induction field \(B\) within and without the solenoid and point out that, in the absence of electric charge that the electric field generated at any point is given by \(E= -{\partial A\over\partial t}\).

Vector potential photoelectron microscopy
Review of Scientific Instruments, 2011A new class of electron microscope has been developed for the chemical microanalysis of a wide range of real world samples using photoelectron spectroscopy. Highly structured, three-dimensional samples, such as fiber mats and fracture surfaces can be imaged, as well as insulators and magnetic materials.

The vector potential revisited
Electrical Engineering in Japan, 1993AbstractThe vector potential in electrodynamics is investigated through the decomposition of its form to the following two parts: 1) the so‐called transverse part represented by a divergenceless vector; and 2) the longitudinal part represented by an irrotational vector.

Up to now, we have met the description of the magnetic field by two differential equations. These two equations are $$ div{\text{ }}B = 0 $$ (9.1) $$ curl{\text{ }}B = \frac{{4\pi }}{c}j $$ (9.2)

Hydrodynamic vector potentials
The European Physical Journal B, 2002Solving the Navier-Stokes equation for incompressible fluids is greatly simplified by the solution of the vorticity equation. To accomplish this for three-dimensional flows requires vector potentials. These potentials are not only useful to take care of the incompressibility.

Proceedings of the 2014 Workshop on Programming models for SIMD/Vector processing, 2014
The importance of vector instructions is growing in modern computers. Almost all architectures include some form of vector instructions and the tendency is for the size of the instructions to grow with newer designs. To take advantage of the performance that these systems offer, it is imperative that programs use these instructions, and yet they do not

The scalar potential φ and the vector potential A
1997Though it is possible to determine the electric and magnetic fields E and B due to varying charge and current distributions by solving the differential equations (1.125) and (1.122) for E and B, for example using the Jefimenko solutions given by equations (1.136) and (1.134), it is sometimes more convenient to solve problems and to interpret ...
