Even though one usually calculates capacitor losses with a complex epsilon it still oÆends the principle of a constant speed of light. Maxwell’s term c2 = 1/"·μ suggests a physically inexplicable complex speed. By such an oÆence against basic principles every physicist is asked to search and to repair the mistake in the textbooks. The contribution clearly explains how vortex losses occur instea...

Elementary processes in QED Scattering amplitudes and the differential cross-section Kinematics of binary processes, decay rate of an unstable particle The scattering e− e → μ− μ, the square of the scattering amplitude Unpolarized scattering and its differential cross-section The scattering e− μ− → e− μ−, the square of the scattering amplitude Crossing symmetry, Mandelstam variables, crossed...

The use of a fermion Green’s function involving no delta functions is demonstrated. This Green’s function is employed to compute the first order contribution to the vacuum polarization of the hydrogen Lamb shift. No infinities appear so that regularization is unnecessary. The numerical value of this contribution to the vacuum polarization is shown to be identical to the value obtained by regula...

We show that it is possible to obtain a realistic and deterministic model, based on a previous work of John Bell, which reproduces the experimental predictions of the orthodox interpretation of quantum electrodynamics. P.A.C.S.: 03.65.Ta; 03.70.+k

I show that the standard approach to modeling phenomena involving microscopic classical electrodynamics is mathematically inconsistent. I argue that there is no conceptually unproblematic and consistent theory covering the same phenomena to which this inconsistent theory can be thought of as an approximation; and I propose a set of conditions for the acceptability of inconsistent theories. 1. I...

We employ the influence functional technique to trace out the photonic contribution from full quantum electrodynamics. The reduced density matrix propagator then is constructed for the electron field. We discuss the role of time-dependent renormalization in the propagator and focus our attention to the possibility of obtaining a dynamically induced superselection rule. As a final application of...

We generalize Wheeler-Feynman electrodynamics with a variational problem for trajectories that are required to merge continuously into given past and future boundary segments. We prove that the boundary-value problem is well posed for two classes of boundary data. The well-posed solution in general has velocity discontinuities, henceforth a broken extremum. Along regular segments, broken extrem...

18. a) Using the results obtained in problem (2.17) above, we are to find a closed-form expression for the Green’s function for the interior of a cylinder of radius b with Dirichlet boundary conditions. From our general work with solutions to the Laplace equation with Green’s functions and from our work about in problem (2.17), we know that the Green’s function for the interior of the cylinder ...

The article contains a review and new results of some mathematical models relevant to the interpretation quantum mechanics emulating well-known gauge theories, such as scalar electrodynamics (Klein–Gordon–Maxwell electrodynamics), spinor (Dirac–Maxwell etc. In these models, evolution is typically described by modified Maxwell equations. case electrodynamics, complex wave function can be made re...

We define symmetries in non-relativistic quantum electrodynamics, which have the physical interpretation of rotation, parity and time reversal symmetry. collect transformation properties related to these Fock space representation as well Schr\"odinger representation. As an application, we generalize improve theorems about Kramer's degeneracy electrodynamics.
