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…
Statistics and UV-IR Mixing with Twisted Poincare Invariance
A. P. Balachandran, T. R. Govindarajan, G. Mangano +3
We elaborate on the role of quantum statistics in twisted Poincare invariant theories. It is shown that, in order to have twisted Poincare group as the symmetry of a quantum theory…
Noncommutative Geometry: Fuzzy Spaces, the Groenewold-Moyal Plane
Aiyalam P. Balachandran, Babar Ahmed Qureshi
In this talk, we review the basics concepts of fuzzy physics and quantum field theory on the Groenwald-Moyal Plane as examples of noncommutative spaces in physics. We introduce the…
Twisted Supersymmetry, Fermion-Boson Mixing and Removal of UV-IR Mixing
B. A. Qureshi
Exact supersymmetry can be maintained on nonanticommutative superspace with a twisted coproduct on the supergroup.We show that the usual exchange statistics for the superfields is…
