Zero point energy on extra dimension: Noncommutative Torus
S. Fabi, B. Harms, G. Karatheodoris
In this paper we calculate the zero point energy density experienced by observers on M^4 due to a massless scalar field defined throughout M^4 x T^2_F, where T^2_F are fuzzy extra…
Dark Energy from Casimir Energy on Noncommutative Extra Dimensions
S. Fabi, B. Harms, G. Karatheodoris
We study the possibility that dark energy is a manifestation of the Casimir energy on extra dimensions with the topology of . We consider our universe to be a…
A supersymmetric model of gamma ray bursts
L. Clavelli, G. Karatheodoris
We propose a model for gamma ray bursts in which a star subject to a high level of fermion degeneracy undergoes a phase transition to a supersymmetric state. The burst is initiated…
Fate of the Born-Infeld solution in string theory
G. Karatheodoris, A. Pinzul, A. Stern
We argue that the Born-Infeld solution on the Dbrane is unstable under inclusion of derivative corrections to Born-Infeld theory coming from string theory. More specifically, w…
