It is well known that the concept of a point charge interacting with the electromagnetic (EM) field has a problem. To address that problem we introduce the concept of wave-corpuscle to describe spinless elementary charges interacting with the classical EM field. Every charge interacts only with the EM field and is described by a complex valued wave function over the 4-dimensional space time continuum. A system of many charges interacting with the EM field is defined by a local, gauge and Lorentz invariant Lagrangian with a key ingredient—a nonlinear self-interaction term providing for a cohesive force assigned to every charge. An ideal wave-corpuscle is an exact solution to the Euler-Lagrange equations describing both free and accelerated motions. It carries explicitly features of a point charge and the de Broglie wave. Our analysis shows that a system of well separated charges moving with nonrelativistic velocities are represented accurately as wave-corpuscles governed by the Newton equations of motion for point charges interacting with the Lorentz forces. In this regime the nonlinearities are “stealthy” and don’t show explicitly anywhere, but they provide for the binding forces that keep localized every individual charge. The theory can also be applied to closely interacting charges as in hydrogen atom where it produces discrete energy spectrum.

The self-force problem of classical electrodynamics has two closely linked facets: The ill defined dynamics of a point charge due to the divergent self field at the position of the charge, and the divergence of formally conserved quantities, such as the energy, associated with symmetries of the corresponding Lagrangian. Fixing the self-force problem amounts to the construction of a \emph{new} theory, which is free of the above pathologies and yet "sufficiently close" to the immensely successful original. In a recent paper by the present author such a proposal, dubbed extended charge dynamics (ECD), was presented. The essential ingredients of classical electrodynamics preserved by ECD (and, among the plethora of solutions to the problem, only by ECD) are: - Ontology. The electromagnetic field is the same unquantized classical field, while charges are sufficiently localized conserved currents, accounting for the manifest corpuscular nature of elementary charges. - Symmetries. ECD enjoys the full symmetry group of classical electrodynamics, most importantly the hidden symmetry of scale covariance. - Conservation laws. All ECD conservation laws formally coincide with their classical counterparts, and yet lead to finite conserved quantities. Despite this seemingly classical setting, and the reduction of ECD to classical electrodynamics in the latter's domain of validity, it is shown in the present paper that ensembles of ECD solutions could, in principle, reproduce the statistical predictions of quantum mechanics. Exclusively quantum mechanical concepts, such as interference, violations of Bell's inequalities, spin and even photons (despite the use of a classical EM field), all emerge as mere statistical manifestations of the self interaction of ECD charges.
Essentially, we solve the particle-field equations obtained in the matter distribution quantum mechanics. In the framework of this theory, a particle is described by a density amplitude function, we call wave function, as a packet of waves with the time dependent phases proportional to the relativistic Lagrangian. The mass quantization of such a particle, as a distribution of matter, is obtained from the equality of the spatial integral of the density with the mass as a characteristic of the relativistic dynamics of this matter. The particle dynamics, as a motion of a mass spatial distribution, is obtained from the equality of the wave propagation velocities with the distribution coordinate velocities. This description is a physical one, compared to the Schrödinger-Heisenberg description leading to unphysical results as a null velocity for the kinetic energy as a constant of motion, or Zitterbewegung. The description of a particle interaction with an electromagnetic field by additional Lagrangian terms, with a vector potential conjugated to coordinates, as in the Aharonov-Bohm effect, and an electric potential conjugated to time, leads to the Lorentz force, and the Maxwell equations. In the two conjugated spaces, of the coordinates and of the momentum, the dynamics of a quantum particle is described by propagation operators, depending on the coordinate-momentum product, applied to time dependent wave functions satisfying matter-field equations. Unlike the standard Schrödinger or Schrödinger-Dirac equations, depending only on the Hamiltonian operator, instead of the Hamiltonian these equations contain the Lagrangian, which, besides the Hamiltonian, include additional terms with an explicit dependence on velocity, as it is expected in a relativistic theory. We obtain the wave function of a particle-antiparticle system interacting with an electromagnetic field, as a wave packet of spinors propagating in space with finite dimensions, given by the finite definition domain of the density function, in the space of the matter-field momentum, as a constant of motion. We show that an electrically charged quantum particle, rotating in a central electric field, generates a vector potential with a magnetic field perpendicular to the rotational plane and an electric field in this plane. By a quantum transition, a photon is emitted in the particle rotational plane, with the magnetic field perpendicular to this plane, and the electric field contained in this plane. In this framework, the vector potential rotation is correlated to a particle momentum rotation, for the canonical matter-field momentum as a constant of motion, without any electromagnetic field radiated outside.
Abstract Steven Weinberg, one of the founders of the Standard Model of Physics, asked years ago [1]: is the wave function of quantum mechanics real, or is it just used by scientists to calculate? We try to find the answer. We study the general solution of the Schrödinger equation mathematically. We will prove that for satisfying the Schrödinger equation, the particle should possess a helical structure of mass density. Then we will prove further that (i) charged elementary particles and atomic nucleus fall into two categories: they have charge or, but different directions of charges helices, like right-handed electron and left-handed electron etc. (ii) Charge (or) distributes double helically on the particle side boundary. It generates and carries a double helix external electric field with the same velocity. (iii) This E-wave will be proved is just the de Broglie wave. (iv) Its function is particle’s state function in quantum mechanics. (v) Charged particle itself and the de Broglie E-wave it carries form a particle-wave hybrid structure. The E -wave exhibits all the possible states and probabilities; as for the particle itself it can take only one basis state randomly, such as at an eigen state in the atom and molecular or at a point on the interference pattern. (vi) The orbital motion of an electron in the lower energy layers of atom and molecule does not radiate EM energy to collapse into the nucleus. (vii) Self-interference of the hybrid structure can better explain the single particle double-slit interference
Relativistic invariant equations are proposed for the action function and the wave function based on the invariance of the representation of the generalized momentum. The equations have solutions for any values of the interaction constant of a particle with a field, for example, in the problem of a hydrogen-like atom, when the atomic number of the nucleus Z > 137. Based on the parametric representation of the action, the expression for the canonical Lagrangian, the equations of motion and the expression for the force acting on the charge during motion in an external electromagnetic field are derived. The Dirac equation with the correct inclusion of the interaction for a particle in an external field is presented. In this form, the solutions of the equations are not limited by the value of the interaction constant. The solutions of the problem of charge motion in a constant electric field, problems for a particle in a potential well, and penetration of a particle through a potential barrier, as well as problem of a hydrogen atom are presented.
In the de Broglie-Bohm formulation of quantum theory, the quantum force exactly cancels the Coulomb attractive force in atomic \emph{s}-states. In this paper it is contended, based on energy conservation, that the force on a charge in a time-advanced electromagnetic field is of opposite sign to the Lorentz force due to the retarded field, and that such an advanced classical electromagnetic force accounts for part of Bohm's quantum force. If Coulomb attraction is negated, then some other mechanism must bind electrons to the nuclei of atoms. It is proposed magnetic interactions between relativistically-moving charges may account for atomic binding without assumption of a Coulomb potential. If charged spin-half particles always move luminally, as the Dirac theory implies, and so moving give rise to the intrinsic magnetic moment, then magnetic spin-spin interactions stronger than currently recognized are to be expected. Part of the magnetic interaction between equal-mass Dirac particles has been previously shown to be radial and inverse-square, of equal strength to Coulomb interaction, and sinusoidally modulated by interparticle separation with a spatial period equal the de Broglie wavelength. The Coulomb-like spin-spin interaction is further elaborated to show explicit correspondence with the de Broglie matter wave and Schrodinger wavefunction. It is proposed spin-spin interactions as expected according to this line of reasoning can properly account for the formation of atoms, if the electromagnetic interaction in atoms is classical and time symmetric, and if quarks and leptons are composed of more-fundamental spin-half particles.
