Vacuum energy, the Casimir effect, and Newton's non-constant
Benjamin Koch, Christian Käding, Mario Pitschmann +1
We explore two hypotheses. First, the possibility that the quantum vacuum energy density of the Casimir effect contributes to a (local) gravitational vacuum energy density. Second,…
Gauge Theories on Deformed Spaces
Daniel N. Blaschke, Erwin Kronberger, Rene I. P. Sedmik +1
The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat…
On Non-Commutative U*(1) Gauge Models and Renormalizability
Daniel N. Blaschke, Arnold Rofner, Rene I. P. Sedmik +1
Based on our recent findings regarding (non-)renormalizability of non-commutative U*(1) gauge theories [arxiv:0908.0467, arxiv:0908.1743] we present the construction of a new type…
On the Problem of Renormalizability in Non-Commutative Gauge Field Models - A Critical Review
Daniel N. Blaschke, Erwin Kronberger, Arnold Rofner +3
When considering quantum field theories on non-commutative spaces one inevitably encounters the infamous UV/IR mixing problem. So far, only very few renormalizable models exist and…
One-Loop Calculations and Detailed Analysis of the Localized Non-Commutative 1/p**2 U(1) Gauge Model
Daniel N. Blaschke, Arnold Rofner, Rene I. P. Sedmik
This paper carries forward a series of articles describing our enterprise to construct a gauge equivalent for the -deformed non-commutative model originally introduced…
Improved Localization of a Renormalizable Non-Commutative Translation Invariant U(1) Gauge Model
Daniel N. Blaschke, Arnold Rofner, Manfred Schweda +1
Motivated by the recent work of Vilar et al. arXiv:0902.2956 we enhance our non-commutative translation invariant gauge model arXiv:0901.1681 by introducing auxiliary fields and gh…
One-Loop Calculations for a Translation Invariant Non-Commutative Gauge Model
Daniel N. Blaschke, Arnold Rofner, Manfred Schweda +1
In this paper we discuss one-loop results for the translation invariant non-commutative gauge field model we recently introduced in arXiv:0804.1914. This model relies on the additi…
Quantum Corrections for Translation-Invariant Renormalizable Non-Commutative Phi^4 Theory
Daniel N. Blaschke, Francois Gieres, Erwin Kronberger +3
In this paper we elaborate on the translation-invariant renormalizable Phi^4 theory in 4-dimensional non-commutative space which was recently introduced by the Orsay group. By expl…
