Coherence lifetimes of excitations in an atomic condensate due to the thin spectrum
T. Birol, T. Dereli, Ö. E. Müstecaplıoğlu +1
We study the quantum coherence properties of a finite sized atomic condensate using a toy-model and the thin spectrum model formalism. The decoherence time for a condensate in the…
Exact Solutions in Five-Dimensional Axi-dilaton Gravity with Euler-Poincare Term
A. N. Aliev, H. Cebeci, T. Dereli
We examine the effective field equations that are obtained from the axi-dilaton gravity action with a second order Euler-Poincare term and a cosmological constant in all higher dim…
Linear Connections on Light-like Manifolds
T. Dereli, S. Kocak, M. Limoncu
It is well-known that a torsion-free linear connection on a light-like manifold compatible with the degenerate metric exists if and only if is a Killing distr…
An Exact Cosmological Solution of the Coupled Einstein-Majorana Fermion-Scalar Field Equations
A. B. Balantekin, T. Dereli
We couple a neutral scalar field and a Majorana fermion field to Einstein gravity represented by the Robertson-Walker metric and find a class of exact cosmological solutions.
