Gauge Orbit Types for Theories with Classical Compact Gauge Group
Alexander Hertsch, Gerd Rudolph, Matthias Schmidt
We determine the orbit types of the action of the group of local gauge transformations on the space of connections in a principal bundle with structure group O(n), SO(n) or …
On the algebra of quantum observables for a certain gauge model
Gerd Rudolph, Matthias Schmidt
We prove that the algebra of observables of a certain gauge model is generated by unbounded elements in the sense of Woronowicz. The generators are constructed from the classical g…
Iterative construction of representations and Lax matrix factorisation
S. Derkachov, D. Karakhanyan, R. Kirschner +1
The construction of a generic representation of or of the trigonomentric deformation of its enveloping algebra known as algebraic induction is conveniently formulated…
Casimir force for a sphere in front of a plane beyond Proximity Force Approximation
M. Bordag, V. Nikolaev
For the configuration of a sphere in front of a plane we calculate the first two terms of the asymptotic expansion for small separation of the Casimir force. We consider both Diric…
Stronger constraints on non-Newtonian gravity from the Casimir effect
V. M. Mostepanenko, R. S. Decca, E. Fischbach +3
We review new constraints on the Yukawa-type corrections to Newtonian gravity obtained recently from gravitational experiments and from the measurements of the Casimir force. Speci…
Polarization tensor of charged gluons in color magnetic background field at finite temperature
M. Bordag, V. Skalozub
We calculate the polarization tensor of charged gluons in a Abelian homogeneous magnetic background field at finite temperature in one loop order Lorentz background field gauge in…
