Noncommutative with Quantized Cosmological Constant
A. Pinzul, A. Stern
We examine a recent deformation of three-dimensional anti-deSitter gravity based on noncommutative Chern-Simons theory with gauge group . In addition to a nonc…

A. P. Balachandran, S. Kurkcuoglu, S. Vaidya
This is a preliminary version, comments and inputs are welcome. Contents: 1. Introduction. 2. Fuzzy Spaces. 3. Star Products. 4. Scalar Fields on the Fuzzy Sphere. 5. Instantons, M…
UV-IR Mixing in Non-Commutative Plane
A. P. Balachandran, A. Pinzul, B. Qureshi
Poincaré-invariant quantum field theories can be formulated on non-commutative planes if the coproduct on the Poincaré group is suitably deformed \cite{Dimitrijevic:2004rf, Chaichi…
Spin and Statistics on the Groenewold-Moyal Plane: Pauli-Forbidden Levels and Transitions
A. P. Balachandran, G. Mangano, A. Pinzul +1
The Groenewold-Moyal plane is the algebra A_θ(R^(d+1)) of functions on R^(d+1) with the star-product as the multiplication law, and the commutator [x_μ,x_ν] =i θ_{μν} between the c…
SUSY anomalies break N=2 to N=1: The supersphere and the fuzzy supersphere
A. P. Balachandran, A. Pinzul, B. Qureshi
The N=1 SUSY on S^2 and its fuzzy finite-dimensional matrix version are known. The latter regulates quantum field theories, and seems suitable for numerical work and capable of hig…
Moduli Stabilization and Inflation Using Wrapped Branes
Damien A. Easson, Mark Trodden
We demonstrate that a gas of wrapped branes in the early Universe can help resolve the cosmological Dine-Seiberg/Brustein-Steinhardt overshoot problem in the context of moduli stab…
