The quantum vacuum at the foundations of classical electrodynamics [PDF]

, 2010
In the classical theory of electromagnetism, the permittivity and the permeability of free space are constants whose magnitudes do not seem to possess any deeper physical meaning.

Boyer-Lindquist space-times and beyond: Meta-material analogues [PDF]

, 2018
Physically reasonable stationary axisymmetric spacetimes can (under very mild technical conditions) be put into Boyer-Lindquist form. Unfortunately a metric presented in Boyer-Lindquist form is not well-adapted to the "quasi-Cartesian" meta-material ...

Dimensions and Units in Electrodynamics [PDF]

, 2004
We sketch the foundations of classical electrodynamics, in particular the transition that took place when Einstein, in 1915, succeeded to formulate general relativity.

Quantum levitation by left-handed metamaterials [PDF]

, 2007
Left-handed metamaterials make perfect lenses that image classical electromagnetic fields with significantly higher resolution than the diffraction limit. Here we consider the quantum physics of such devices.

Photon Self-Energy in a Color Superconductor [PDF]

, 2001
In a color superconductor the diquark condensates break spontaneously both the color and ordinary electromagnetism, leaving a remanining rotated U(1) symmetry unbroken.

A posteriori error estimation for stochastic static problems [PDF]

, 2014
To solve stochastic static field problems, a discretization by the Finite Element Method can be used. A system of equations is obtained with the unknowns (scalar potential at nodes for example) being random variables. To solve this stochastic system, the

Negative Refraction and Left-handed electromagnetism in Microwave Photonic Crystals [PDF]

, 2004
We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical ...

Volume integral equations for electromagnetic scattering in two dimensions

, 2015
We study the strongly singular volume integral equation that describes the scattering of time-harmonic electromagnetic waves by a penetrable obstacle.

Gravitomagnetic Moments and Dynamics of Dirac's (spin 1/2) fermions in flat space-time Maxwellian Gravity

, 2003
The gravitational effects in the relativistic quantum mechanics are investigated in a relativistically derived version of Heaviside's speculative Gravity (in flat space-time) named here as Maxwellian Gravity.

Canonical quantization of macroscopic electromagnetism [PDF]

, 2010
Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption.
