Kaluza-Klein Pistons with non-Commutative Extra Dimensions
Abstract
We calculate the scalar Casimir energy and Casimir force for a Kaluza-Klein piston setup in which the extra dimensional space contains a non-commutative 2-sphere, . The cases to be studied are and respectively as extra dimensional spaces, with the dimensional commutative torus. The validity of the results and the regularization that the piston setup offers are examined in both cases. Finally we examine the 1-loop corrected Casimir energy for one piston chamber, due to the self interacting scalar field in the non-commutative geometry. The computation is done within some approximations. We compare this case for the same calculation done in Minkowski spacetime . A discussion on the stabilization of the extra dimensional space within the piston setup follows at the end of the article.
