Chameleon mechanism with a new potential
Source: Astrophysics and Space Science, Volume 333, Number 2, June 2011 , pp. 501-505(5)
Abstract:Chameleon scalar field is a new model, which introduced to provide a mechanism for exhibiting accelerating universe. Chameleon field has several interesting aspects, such as field dependence on the local matter density. For this model we introduce a new kind of potential which has run away form and satisfies chameleon constraints. The results are acceptable in comparison with the other potentials which studied up to now.
