The effects of physical interactions are usually incorporated into the quantum theory by including the corresponding terms in the Hamiltonian. Here we consider the effects of including the gravitational potential energy of massive particles in the Hamiltonian of quantum electrodynamics. This results in a predicted correction to the speed of light that is proportional to the fine structure constant. The correction to the speed of light obtained in this way depends on the gravitational potential… Expand
Numerical calculation of the relativistic acceleration of an electron in curved spacetime using the Dirac equation
The relativistic acceleration of an electron in a uniform gravitational field is calculated numerically using the generalization of the Dirac equation to curved spacetime. Equivalent results are alsoExpand
Non-relativistic model for interaction of dark particles with matter
A non-relativistic quantum mechanical model for interaction of dark particles with matter is proposed; the model describes resonant amplification of effective interaction between two massive bodiesExpand
Neutrinos and v < c
The Stueckelberg formulation of a manifestly covariant relativistic classical and quantum mechanics is briefly reviewed and it is shown that in this framework a simple (semiclassical) model existsExpand
Focus on gravitational quantum physics
The interplay between quantum theory and gravity remains one of the least explored fields of physics. The current 'focus on' collection summarises experimental and theoretical results from many ofExpand
Magnetism as an Electric Angle-effect and Gravitation as an Electric Effect
At first, I regard magnetism. I can show that the magnetic force is an electric angle-effect by establishing two postulates: the dependence of the electric force on the velocity, and the existence ofExpand
A New Set of Maxwell-Lorentz Equations and Rediscovery of Heaviside-Maxwellian (Vector) Gravity from Quantum Field Theory
We show that if we start with the free Dirac Lagrangian, and demand local phase invariance, considering the total phase coming from two independent contributions associated with the charge and massExpand
Dispersion properties, nonlinear waves and birefringence in classical nonlinear electrodynamics
Using the very basic physics principles, we have studied the implications of quantum corrections to classical electrodynamics and the propagation of electromagnetic waves and pulses. The initialExpand
On the Origin of Magnetism and Gravitation and on the Nature of Electricity and Matter
This is a significantly improved resumption of my previous paper on gravitation [40]. I can show in a improved way that gravitation is an electric effect. To this, it is necessary to betterExpand
Nonlinear Waves and Coherent Structures in Laser Induced Plasmas and Polarized Vacuum

Cherenkov Radiation Effect in Vacuum
The Cherenkov effect usually occurs in a certain medium. In this medium, such as water, the speed of particles exceeds the speed of light in the medium, which will produce observable CherenkovExpand

We calculate in QED the contribution to the photon effective action from one-loop vacuum polarization on a general curved background manifold, and use it to investigate the corrections to the localExpand
