Quantum cosmology with k-Essence theory (1604.00624v2)
Published 3 Apr 2016 in gr-qc, astro-ph.CO, and hep-th
Abstract: A class of $k$-Essence cosmological models, with a power law kinetic term, is quantised in the mini-superspace. It is shown that for a specific configuration, corresponding to a pressureless fluid, a Schr\"odinger-type equation is obtained with the scalar field playing the r^ole of time. The resulting quantum scenario reveals a bounce, the classical behaviour being recovered asymptotically.
