The local covariant continuum action of an SU(2) gauge theory in covariant Abelian gauges is investigated. It describes the critical limit of an Abelian Lattice Gauge Theory (LGT) with an equivariantâ€¦ (More)

An equivariant BRST-construction is used to define the continuum SU(3) gauge theory on a finite torus. I corroborate previous results using renormalization group techniques by explicitly computingâ€¦ (More)

The Casimir energy of a massless scalar field is semiclassically given by contributions due to classical periodic rays. The required subtractions in the spectral density are determined explicitly.â€¦ (More)

I construct a Lattice Gauge Theory (LGT) with discrete Z2 structure group and an equivariant BRST symmetry that is physically equivalent to the standard SU(2)-LGT. The measure of this Z2-LGT isâ€¦ (More)

The electromagnetic Casimir energies of a spherical and a cylindrical cavity are analyzed semiclassically. The field theoretical self-stress of a spherical cavity with ideal metallic boundaryâ€¦ (More)

It is proven that the " horizon condition " , which was found to characterize the fundamental modular region in continuum theory and the thermody-namic limit of gauge theory on a periodic lattice,â€¦ (More)

The free energy of U(N) gauge theory is expanded about a center-symmetric topological background configuration with vanishing action and vanishing Polyakov loops. We construct this background forâ€¦ (More)

We discuss a micro-economically inspired model for the prices of futures contracts for the delivery of electrical power. Such financial markets have been created to stimulate the competition in theseâ€¦ (More)

We present a detailed experimental and theoretical study of edge enhancement in optically pumped Rb vapor in coated cylindrical pyrex glass cells. The Zeeman polarization of Rb atoms is produced andâ€¦ (More)

We derive the semiclassical approximation to Feynman's path integral representation of the energy Green function of a massless particle in the shadow region of an ideal obstacle in a medium. Theâ€¦ (More)
