标题： Inflationary universe in loop quantum cosmology

摘要： 圈量子宇宙学通过高能区域的大反弹机制很好地避免了大爆炸奇点，这是一个很好的解决方案。 在圈量子宇宙学中，无论宇宙中填充何种物质成分，在大反弹之后都会出现一个膨胀的宇宙。 在反弹后的初始阶段会出现一种没有幻影物质的超级膨胀阶段；然后宇宙将经历正常的膨胀阶段。 我们在此框架内详细讨论了膨胀的条件。 此外，对于慢滚膨胀，我们预计圈量子宇宙学的影响应该会在原始扰动功率谱中留下印记。 然而，我们表明这种印记太弱而无法被观测到。 显示英文摘要

摘要： Loop quantum cosmology provides a nice solution of avoiding the big bang singularity through a big bounce mechanism in the high energy region. In loop quantum cosmology an inflationary universe is emergent after the big bounce, no matter what matter component is filled in the universe. A super-inflation phase without phantom matter will appear in a certain way in the initial stage after the bounce; then the universe will undergo a normal inflation stage. We discuss the condition of inflation in detail in this framework. Also, for slow-roll inflation, we expect the imprint from the effects of the loop quantum cosmology should be left in the primordial perturbation power spectrum. However, we show that this imprint is too weak to be observed.
