Direction-Dependent CMB Power Spectrum and Statistical Anisotropy from Noncommutative Geometry
Earnest Akofor, A. P. Balachandran, Sang G. Jo +2
Modern cosmology has now emerged as a testing ground for theories beyond the standard model of particle physics. In this paper, we consider quantum fluctuations of the inflaton sca…
S-Matrix on the Moyal Plane: Locality versus Lorentz Invariance
A. P. Balachandran, A. Pinzul, B. A. Qureshi +1
Twisted quantum field theories on the Groenewold-Moyal plane are known to be non-local. Despite this non-locality, it is possible to define a generalized notion of causality. We sh…
Twisted Gauge and Gravity Theories on the Groenewold-Moyal Plane
A. P. Balachandran, A. Pinzul, B. A. Qureshi +1
Recent work [hep-th/0504183,hep-th/0508002] indicates an approach to the formulation of diffeomorphism invariant quantum field theories (qft's) on the Groenewold-Moyal (GM) plane.…
Twisted Poincaré Invariant Quantum Field Theories
A. P. Balachandran, A. Pinzul, B. A. Qureshi
It is by now well known that the Poincaré group acts on the Moyal plane with a twisted coproduct. Poincaré invariant classical field theories can be formulated for this twisted cop…
Interacting Quantum Topologies and the Quantum Hall Effect
A. P. Balachandran, Kumar S. Gupta, Seckin Kurkcuoglu
The algebra of observables of planar electrons subject to a constant background magnetic field B is given by A_theta(R^2) x A_theta(R^2) the product of two mutually commuting Moyal…
Quantum Fields on the Groenewold-Moyal Plane: C, P, T and CPT
E. Akofor, A. P. Balachandran, S. G. Jo +1
We show that despite the inherent non-locality of quantum field theories on the Groenewold-Moyal (GM) plane, one can find a class of , , and …
Quantum Fields with Noncommutative Target Spaces
A. P. Balachandran, A. R. Queiroz, A. M. Marques +1
Quantum field theories (QFT's) on noncommutative spacetimes are currently under intensive study. Usually such theories have world sheet noncommutativity. In the present work, inste…
