标题： Quantum cosmology with k-Essence theory

摘要： 一类带有幂律动能项的$k$-Essence 宇宙学模型在小超空间中被量子化。 显示对于特定配置，对应于无压流体，得到一个薛定谔型方程，标量场扮演时间的角色。 所得到的量子情景显示出一个反弹，经典行为在渐近情况下被恢复。 显示英文摘要

摘要： 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.
