We analyze wave propagation in the vacuum of Podolsky regularized electrodynamics. Two kinds of waves were found in the theory: the traditional non-dispersive waves of Maxwell electrodynamics, and a dispersive wave reminiscent of wave propagation in a collisionless plasma. Charged particle concentration was determined, and found to be huge in this vacuum. We interpret the results in terms of vacuum polarization effects induced in an otherwise classical theory.

Green functions and propagation in the Bopp–Podolsky electrodynamics
A conducting surface in Lee–Wick electrodynamics
Lee–Wick electrodynamics in the vicinity of a conducting plate is investigated. The propagator for the gauge field is calculated and the interaction between the plate and a point-like electric charge
Some Considerations About Podolsky-Axionic Electrodynamics
For a Podolsky-axionic electrodynamics, we compute the interaction potential within the structure of the gauge-invariant but path-dependent variables formalism. The result is equivalent to that of
Dirichlet boundary condition for the Lee–Wick-like scalar model
Lee-Wick-like scalar model near a Dirichlet plate is considered in this work. The modified propagator for the scalar field due to the presence of a Dirichlet boundary is computed, and the interaction
Second Gradient Electromagnetostatics: Electric Point Charge, Electrostatic and Magnetostatic Dipoles
The theory of second gradient electromagnetostatics delivers a singularity-free electromagnetic field theory with weak spatial nonlocality, based on higher-order partial differential equations based on Lorentz and U(1)-gauge invariant.
Three arguable and interrelated concepts: point particle singularity, asymmetric action of EM on quantum wave functions, and the Left out restricted Lorentz gauge from U(1)
We address three issues. i. The point particle assumption inherent to non-quantum physics is singular and entails divergent fields and integrals. ii. In quantum physics EM plays an asymmetric roll.
Vector dark energy models with quadratic terms in the Maxwell tensor derivatives
We consider a vector–tensor gravitational model with terms quadratic in the Maxwell tensor derivatives, called the Bopp–Podolsky term. The gravitational field equations of the model and the equations
Relating renormalizability of D-dimensional higher-order electromagnetic and gravitational models to the classical potential at the origin
Simple prescriptions for computing the D-dimensional classical potential related to electromagnetic and gravitational models, based on the functional generator, are built out. These recipes are

It is shown that in the regularized Maxwell theory, the point particle limit is finite and well defined, and the electromagnetic mass of a point particle enters the equation of motion in a form consistent with the special theory of relativity.
Motion of Extended Charges in Classical Electrodynamics
The Lorentz–Dirac theory of radiation reaction on the motion of point charges is beset by the well known problems of runaway solutions and preacceleration. We examine the classical theory of extended
Solutions of Podolsky's electrodynamics equation in the first-order formalism
The Podolsky generalized electrodynamics with higher derivatives is formulated in the first-order formalism. The first-order relativistic wave equation in the 20-dimensional matrix form is derived.
Absence of runaways and divergent self-mass in nonrelativistic quantum electrodynamics
We derive the quantum-mechanical operator equation of motion for a point electron and show that (i) the electrostatic self-mass of a point electron is zero in quantum mechanics; (ii) the equation of
Radiation Reaction in Nonrelativistic Quantum Electrodynamics
We derive the Heisenberg operator equation of motion for a nonrelativistic point electron coupled to the quantized electromagnetic field, including radiation reaction. The derivation proceeds in
A relativistic cut-off for classical electrodynamics
Ordinarily it is assumed that interaction between charges occurs along light cones, that is, only where the four-dimensional interval s2=t2-r2 is exactly zero. We discuss the modifications produced
How can one probe Podolsky Electrodynamics

Under rather general assumptions it is proved that the construction of such an algebra is not possible and therefore the quantization condition cannot be derived and this points to the conclusion that the Dirac monopole and the finite photon mass cannot coexist within one and the same theory.
Within the framework of linear quantum field theories, a general study is presented of the existence and removal of runaway modes—solutions of the equations of motion which exhibit a real exponential
Finite Self —Energies in Radiation Theory. Part II
The “cutting-off method” proposed in Part I is equivalent to a field theory basedon Maxwell’s equations supplemented by Yukawa’s equations, both fields having the samepoint charges as sources. The
