# Curvature force and dark energy

@article{Balakin2003CurvatureFA, title={Curvature force and dark energy}, author={Alexander B. Balakin and Diego Pav{\'o}n and Dominik J. Schwarz and Winfried Zimdahl}, journal={New Journal of Physics}, year={2003}, volume={5}, pages={85-85} }

A curvature self-interaction of the cosmic gas is shown to mimic a cosmological constant or other forms of dark energy, such as a rolling tachyon condensate or a Chaplygin gas. Any given Hubble rate and deceleration parameter can be traced back to the action of an effective curvature force on the gas particles. This force self-consistently reacts back on the cosmological dynamics. The links between an imperfect fluid description, a kinetic description with effective antifriction forces and…
