The four fixed points of scale invariant single field cosmological models
BingKan Xue
We introduce a new set of flow parameters to describe the time dependence of the equation of state and the speed of sound in single field cosmological models. A scale invariant pow…

Evolution of curvature and anisotropy near a nonsingular bounce
BingKan Xue, Paul J. Steinhardt
We consider bouncing cosmologies in which an ekpyrotic contraction phase with w >> 1 is followed by a bouncing phase with w < -1 that violates the null energy condition. The bounci…

Unstable growth of curvature perturbation in non-singular bouncing cosmologies
BingKan Xue, Paul J. Steinhardt
We consider non-singular bouncing cosmologies, such as the new ekpyrotic model, in which the universe undergoes a slow contraction phase with equation of state , followed…
