The Maxwell equations as a Bäcklund transformation

open access: yesAdvanced Electromagnetics, 2015
Bäcklund transformations (BTs) are a useful tool for integrating nonlinear partial differential equations (PDEs). However, the significance of BTs in linear problems should not be ignored.

Derivation of the Vlasov–Maxwell system from the Maxwell–Schrödinger equations with extended charges

open access: yesForum of Mathematics, Sigma
We consider the Maxwell–Schrödinger equations in the Coulomb gauge describing the interaction of extended fermions with their self-generated electromagnetic field.

Planar ringlike vortices

open access: yesPhysics Letters B, 2018
We investigate the presence of vortex structures in generalized Maxwell–Higgs and Chern–Simons–Higgs models in the three-dimensional spacetime. Despite the important difference between the Maxwell and Chern–Simons dynamics, we have been able to introduce

Perturbative variational formulation of the Vlasov-Maxwell equations

open access: yes, 2018
The perturbative variational formulation of the Vlasov-Maxwell equations is presented up to third order in the perturbation analysis. From the second and third-order Lagrangian densities, respectively, the first-order and second-order Vlasov-Maxwell ...

Perturbation Method for Particle-like Solutions of the Einstein-Dirac-Maxwell Equations [PDF]

open access: yes, 2009
The aim of this Note is to prove by a perturbation method the existence of solutions of the coupled Einstein-Dirac-Maxwell equations for a static, spherically symmetric system of two fermions in a singlet spinor state and with the electromagnetic ...
