Causality between conducting plates

Causality Between Conducting Plates*

. A two-loop QED effect, uncovered by Scha.rnhorst, causes the phase and group velocities of an electromagnetic wave with w << m, to slightly exceed c, when the wave is travelling in vacua between, and perpendicular to, two parallel conducting plates. Using causal rather than Feynma.n graphs, we show that the wavefront still travels at exactly c. The two-loop effect thus poses no threat to caus...

Comments on the electron anomalous magnetic moment between conducting plates.

Electric Double-Layer Interaction between Dissimilar Charge-Conserved Conducting Plates.

Small metallic particles used in forming nanostructured to impart novel optical, catalytic, or tribo-rheological can be modeled as conducting particles with equipotential surfaces that carry a net surface charge. The value of the surface potential will vary with the separation between interacting particles, and in the absence of charge-transfer or electrochemical reactions across the particle s...

Unsteady Flow of a Dusty Conducting Fluid Between Parallel Porous Plates With Temperature Dependent Viscosity

This paper studies unsteady laminar flow of dusty conducting fluid between parallel porous plates with temperature dependent viscosity. The fluid is acted upon by a constant pressure gradient and an external uniform magnetic field is applied perpendicular to the plates. The parallel plates are assumed to be porous and subjected to a uniform suction from above and injection from below. The visco...

Lamb shift in non-degenerate energy level systems placed between two infinite parallel conducting plates

In this paper, the Lamb shift in systems with non-degenerate energy levels, put in the electromagnetic environment provided by two infinite parallel conducting plates, is analyzed. An explicit formula giving the relative Lamb shift (as compared to the standard one in vacuum) is derived for spherical semiconductor Quantum Dots (QD), via a careful mathematical treatment of divergences in the calc...
