Oscillating dark energy: a possible solution to the problem of eternal acceleration
arXiv:astro-ph/0311535 · doi:10.1103/PhysRevD.68.123501
Abstract
We present a dark energy model with a double exponential potential for a minimally coupled scalar field, which allows general exact integration of the cosmological equations. The solution can perfectly emulate a $Î$-term model at low-medium redshift, exhibits tracking behavior, and does not show eternal acceleration.
