Attractors and Isocurvature Perturbations in Quintessence Models
arXiv:astro-ph/0101014 · doi:10.1103/PhysRevD.64.083513
Abstract
We investigate the evolution of cosmological perturbations in scenarios with a quintessence scalar field, both analytically and numerically. In the tracking regime for quintessence, we find the long wavelength solutions for quintessential perturbations. We discuss the possibility of isocurvature modes generated by the quintessence sector and their impact on observations.
