Quantum cosmology with k-Essence theory
  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.
