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…
QED on the Groenewold Moyal Plane
A. P. Balachandran, B. A. Qureshi, A. Pinzul +1
We investigate a version of noncommutative QED where the interaction term, although natural, breaks the spin-statistics connection. We calculate and $γ+ e^…
Deformed Kac-Moody and Virasoro Algebras
A. P. Balachandran, A. R. Queiroz, A. M. Marques +1
Whenever the group acts on an algebra $\calA$, there is a method to twist to a new algebra $\calA_θ$ which depends on an antisymmetric matrix ($θ^{μν}=-θ^{νμ}=\…
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…
Noncommutative Two Dimensional Gravities
A. P. Balachandran, T. R. Govindarajan, K. S. Gupta +1
We give formulations of noncommutative two dimensional gravities in terms of noncommutative gauge theories. We survey their classical solutions and show that solutions of the corre…
