Causal Space-Times on a Null Lattice
Martin Schaden
I investigate a discrete model of quantum gravity on a causal null-lattice with \SLC structure group. The description is geometric and foliates in a causal and physically transpare…
Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO and CH molecules near surfaces and thin films
Priyadarshini Thiyam, Prachi Parashar, K. V. Shajesh +7
In order to understand why carbon dioxide (CO) and methane (CH) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polariz…
The Dyson-Schwinger equation of a link variable in lattice Landau gauge theory
Andre Sternbeck, Martin Schaden, Valentin Mader
We derive the Dyson-Schwinger equation of a link variable in SU(n) lattice gauge theory in minimal Landau gauge and confront it with Monte-Carlo data for the different terms. Preli…
Poincare' Symmetry of the GZ-Model
Martin Schaden, Daniel Zwanziger
Due to internal symmetries of its ghost sector, the Poincare' generators of the GZ-model are not unique. The model apparently has two linearly independent symmetric and conserved e…
BRST Cohomology and Physical Space of the GZ Model
Martin Schaden, Daniel Zwanziger
We address the issue of BRST symmetry breaking in the GZ model, a local, renormalizable, non-perturbative approach to QCD. Explicit calculation of several examples reveals that BRS…
Perturbative Roughness Corrections to Electromagnetic Casimir Energies
Hua Yao Wu, Martin Schaden
Perturbative corrections to the Casimir free energy due to macroscopic roughness of dielectric interfaces are obtained in the framework of an effective low-energy field theory. It…
