Universal Properties of Nonlinearly Perturbed Maxwell Theory
Tengyang Liu, Yisong Yang
We show that a general nonlinearly perturbed Maxwell theory of electromagnetism possesses three universal fundamental properties: (i) A finite-energy electric point charge. (ii) Ex…
The Effective Radius of an Electric Point Charge in Nonlinear Electrodynamics
Tengyang Liu, Yisong Yang
Motivated by the century-old problem of modeling the electron as a pointlike particle with finite self energy, we develop a new class of nonlinear perturbations of Maxwell's electr…
The Maxwell--Born--Infeld Theory: Presence of Finite-Energy Electric Point Charge and Absence of Monopole and Dyon
Tengyang Liu, Yisong Yang
We formulate a nonlinear electrodynamic theory which may be viewed as a weighted theory minimally interpolating the classical Maxwell and Born--Infeld theories. We show that, in co…
Exact Solutions to the Nonlinear Governing Equations of the Born-Infeld Theory
Yisong Yang
Exact finite-energy solutions to the nonlinear governing equations of the Born-Infeld theory of electrodynamics, describing continuous distributions of electric, magnetic, and dyon…
