Quintessence or Phantom: Study of scalar field dark energy models through a general parametrization of the Hubble parameter
Nandan Roy, Sangita Goswami, Sudipta Das
In this work we propose a simple general parametrization scheme of the Hubble parameter for the scalar field dark energy models. In our approach it is possible to incorporate both…
Generalized particle dynamics in anti de Sitter spaces: A source for dark energy
Sudipta Das, Subir Ghosh, Jan-Willem van Holten +1
We consider the generalized particle dynamics, proposed by us, in brane world formalisms for an asymptotically anti de Sitter background. The present framework results in a new mod…
Non-Minimal Quintessence With Nearly Flat Potential
Anjan A Sen, Gaveshna Gupta, Sudipta Das
We consider Brans-Dicke type nonminimally coupled scalar field as a candidate for dark energy. In the conformally transformed Einstein's frame, our model is similar to {\it coupled…
