Dynamics of interacting dark energy model in Einstein and Loop Quantum Cosmology
arXiv:0808.3482 · doi:10.1103/PhysRevD.78.123503
Abstract
We investigate the background dynamics when dark energy is coupled to dark matter in the universe described by Einstein cosmology and Loop Quantum Cosmology. We introduce a new general form of dark sector coupling, which presents us a more complicated dynamical phase space. Differences in the phase space in obtaining the accelerated scaling attractor in Einstein cosmology and Loop Quantum Cosmology are disclosed.
