Dark Energy from Casimir Energy on Noncommutative Extra Dimensions
We study the possibility that dark energy is a manifestation of the Casimir energy on extra dimensions with the topology of S. We consider our universe to be M × S and modify the geometry by introducing noncommutativity on the extra dimensions only, i.e. replacing S with the fuzzy version S F . We find the energy density as a function of the size of the representation M +1 of the algebra of S F...
متن کاملCasimir Force in Compact Noncommutative Extra Dimensions and Radius Stabilization
We compute the one loop Casimir energy of an interacting scalar field in a compact noncommutative space of R × T 2 θ , where we have ordinary flat 1 + d dimensional Minkowski space and two dimensional noncommuative torus. We find that next order correction due to the noncommutativity still contributes an attractive force and thus will have a quantum instability. However, the case of vector fiel...
متن کاملDark Energy as Evidence for Extra Dimensions
It is argued that fluctuations of quantum fields in four-dimensional space do not give rise to dark energy, but are rather a negligible contribution to dark matter. By (relativistic) dark matter we mean that the relation between pressure and energy density is p = 1 3 u, while dark energy is characterized by p = −u. A possible source of dark energy are the fluctuations in quantum fields, includi...

متن کاملTheories with Extra Dimensions
We review some aspects of theories with compact extra dimensions. We consider the motivation and the theoretical basis of Large, Universal and Warped Extra Dimensions. We focus on those aspects that are potentially relevant in the phenomenology at colliders. THE NEED FOR PHYSICS BEYOND THE STANDARD MODEL Although the Standard Model (SM) is in quite good agreement with experiment so far, there a...
