Scalar field exact solutions for non-flat FLRW cosmology: A technique from non-linear Schrödinger-type formulation
摘要：
本文提出了一种非线性薛定谔（NLS）型方程求解非平坦正压流体FLRW宇宙中正则标量场精确解的方法，并与标准Friedmann框架下的方法进行了比较.我们考虑幻影和非幻影标量场的情况下，指数和幂律加速膨胀。并对两种膨胀情况下的有效状态方程进行了分析。我们推测和评论的一些优点和缺点，使用NLS制定解决的精确解。
英文摘要：
We report a method of solving for canonical scalar field exact solution in a non-flat FLRW universe with barotropic fluid using non-linear Schrödinger (NLS)-type formulation in comparison to the method in the standard Friedmann framework. We consider phantom and non-phantom scalar field cases with exponential and power-law accelerating expansion. Analysis on effective equation of state to both cases of expansion is also performed. We speculate and comment on some advantage and disadvantage of using the NLS formulation in solving for the exact solution.
