Constraints from CMB on Spacetime Noncommutativity and Causality Violation
Earnest Akofor, A. P. Balachandran, Anosh Joseph +2
We try to constrain the noncommutativity length scale of the theoretical model given in Ref. [1] using the observational data from ACBAR, CBI and five year WMAP. The noncommutativi…
Twisted Poincare Invariance, Noncommutative Gauge Theories and UV-IR Mixing
A. P. Balachandran, A. Pinzul, A. R. Queiroz
In the absence of gauge fields, quantum field theories on the Groenewold-Moyal (GM) plane are invariant under a twisted action of the Poincare group if they are formulated followin…
Quantum Fields on the Groenewold-Moyal Plane
Earnest Akofor, A. P. Balachandran, Anosh Joseph
We give an introductory review of quantum physics on the noncommutative spacetime called the Groenewold-Moyal plane. Basic ideas like star products, twisted statistics, second quan…
