External gauge field coupled quantum dynamics: gauge choices, Heisenberg algebra representations and gauge invariance in general, and the Landau problem in particular
Jan Govaerts
Even though its classical equations of motion are then left invariant, when an action is redefined by an additive total derivative or divergence term (in time, in the case of a mec…
The Gravito-Electromagnetic Approximation to the Gravimagnetic Dipole and its Velocity Rotation Curve
Jan Govaerts
In view of the observed flat rotation curves of spiral galaxies and motivated by the simple fact that within newtonian gravity a stationary axisymmetric mass distribution or dark m…
Magnetic Monopoles with No Strings Attached: A Portal to the Dark Side of Dual Electrodynamics
Jan Govaerts
It has long been known that in the absence of electric charges and currents, Maxwell's electromagnetism in 4 dimensional vacuum Minkowski space-time is invariant under SO(2) dual t…
Noether Symmetries, Dynamical Constants of Motion, and Spectrum Generating Algebras
Daddy Balondo Iyela, Jan Govaerts
When discussing consequences of symmetries of dynamical systems based on Noether's first theorem, most standard textbooks on classical or quantum mechanics present a conclusion sta…
Deformed Hopfion-Rañada Knots in ModMax Electrodynamics
Clémentine Dassy, Jan Govaerts
Source-free so-called ModMax theories of nonlinear electrodynamics in the four dimensional Minkowski spacetime vacuum are the only possible continuous deformations -- and as a func…
Time Dependent Conserved Charges and their Gauging -- A Modest Case Study in Shared Memory of Victor --
Jan Govaerts
There exist instances of dynamical systems possessing symmetry transformations of which the conserved Noether charges generating these symmetries feature an explicit time dependenc…
