Discerning Noncommutative Extra Dimensions
- Physics
- 2002
Experimental limits on the violation of four-dimensional Lorentz invariance imply that noncommutativity among ordinary spacetime dimensions must be small. Noncommutativity among extra, compactified…
The three-dimensional noncommutative Gross–Neveu model
- Physics
- 2007
This work is dedicated to the study of the noncommutative Gross–Neveu model. As is known, in the canonical Weyl–Moyal approach the model is inconsistent, basically due to the separation of the…
Noncommutativity and unitarity violation in gauge boson scattering
- Physics
- 2002
We examine the unitarity properties of spontaneously broken noncommutative gauge theories. We find that the symmetry breaking mechanism in the noncommutative standard model of Chaichian et al. leads…
Phenomenology of noncommutative field theories
- Physics
- 2004
Experimental limits on the violation of four-dimensional Lorentz invariance imply that noncommutativity among ordinary spacetime dimensions must be small. In this talk, I review the most stringent…
Dilaton cosmology, noncommutativity, and generalized uncertainty principle
- Mathematics
- 2008
The effects of noncommutativity and of the existence of a minimal length on the phase space of a dilatonic cosmological model are investigated. The existence of a minimum length results in the…
Anomaly freedom in Seiberg-Witten noncommutative gauge theories
- Geology
- 2003
We show that noncommutative gauge theories with arbitrary compact gauge group defined by means of the Seiberg-Witten map have the same one-loop anomalies as their commutative counterparts. This is…
Possible Effects of Noncommutative Geometry on Weak CP Violation and Unitarity Triangles
- Physics
- 2002
The possible effects of noncommutative geometry on weak CP violation and unitarity triangles are discussed by taking into account a simple version of the momentum-dependent quark mixing matrix in the…

Phenomenology, astrophysics and cosmology of theories with submillimeter dimensions and TeV scale quantum gravity
- Physics
- 1999
We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale.…
Hydrogen atom spectrum and the lamb shift in noncommutative QED.
- PhysicsPhysical review letters
- 2001
The results show deviations from the usual QED both on the classical and the quantum levels, and on both levels, the deviations depend on the parameter of space/space noncommutativity.
Limit on Lorentz and CPT violation of the proton using a hydrogen maser
- Physics
- 2001
We present a new measurement constraining Lorentz and $\mathrm{CPT}$ violation of the proton using a hydrogen maser double resonance technique. A search for hydrogen Zeeman frequency variations with…
