Vector potential of the Coulomb gauge
نویسنده
چکیده
The vector decomposition theorem of Helmholtz leads to a form of the Coulomb gauge in which the potentials are expressed in a form that is totally instantaneous. The scalar potential is expressed in terms of the instantaneous charge density, the vector potential in terms of the instantaneous magnetic field.

Comment on ‘Vector potential of the Coulomb gauge’*
The expression for the Coulomb-gauge vector potential in terms of the ‘instantaneous’ magnetic field derived by Stewart (2003 Eur. J. Phys. 24 519) by employing Jefimenko’s equation for the magnetic field and Jackson’s formula for the Coulomb-gauge vector potential can be proven much more simply. In a recent paper [1], Stewart has derived the following expression for the Coulomb-gauge vector po...
متن کاملPotentials of a uniformly moving point charge in the Coulomb gauge *
The Coulomb-gauge vector potential of a uniformly moving point charge is obtained by calculating the gauge function for the transformation between the Lorenz and Coulomb gauges. The expression obtained for the difference between the vector potentials in the two gauges is shown to satisfy a Poisson equation to which the inhomogeneous wave equation for this quantity can be reduced. The right-hand...
متن کاملMesons and diquarks in Coulomb-gauge QCD
I demonstrate how confinement in Coulomb-gauge QCD makes quark-quark states of the color anti-triplet (diquarks) move out of the physical spectrum. Mesons as color singlet quark-antiquark states, on the other hand have finite masses and for highly excited states in the meson spectra effective restoration of chiral symmetry can be observed. In Coulomb-gauge QCD the 00-component of the gluon prop...
متن کاملSynthetic electric fields and phonon damping in carbon nanotubes and graphene
Within the Dirac theory of the electronic properties of graphene, smoothly varying lattice strain affects the Dirac carriers through a synthetic gauge field. For static lattice strain, the gauge field induces a synthetic magnetic field which is known to suppress weak localization corrections by a dynamical breaking of timereversal symmetry. When the lattice strain is time dependent, as in conne...
متن کاملOn the gauge dependence of the singlet and adjoint potentials
We study gauge dependence of the recently suggested definition of the singlet and adjoint potentials in SU(2) lattice gauge theory. We find that in the (time local) maximal tree axial gauge the singlet potential obtained from the gauge dependent correlator TrL(x)L(y) differs from that computed in the Coulomb gauge. In the generalized Coulomb gauge we find the range of the parameter values in wh...
