Chimento和Jakubi（1996 Int. J. Mod. Phys. D 5 71-84）提出的导出Friedmann-Robertson-步行者（FRW）解的方法被推广到考虑暗能量和暗物质之间基于作用量原理的非最小耦合的模型。找到了新的FRW的精解和幻影（平坦）解，并讨论了它们的物理意义。此外，上述方法被修改，使得可以容易地导出“无重合”的解决方案。此外，我们回顾了幻影屏障穿越的一些方面。在这方面，我们提出了一个模型，这是免费的符合问题，并在同一时间，在后期的幻影障碍ω = −1的交叉。最后，我们对有或没有能量转移的标量场宇宙学模型的非预言性质给出了额外的评论。
A method for deriving Friedmann–Robertson–Walker (FRW) solutions developed in Chimento and Jakubi (1996 Int. J. Mod. Phys. D 5 71–84) is generalized to account for models with non-minimal coupling between the dark energy and the dark matter that are based on an action principle. New quintessence and phantom (flat) FRW solutions are found. Their physical significance is discussed. Additionally, the aforementioned method is modified so that, ‘coincidence-free’ solutions can be readily derived. Besides, we review some aspects of the phantom barrier crossing. In this regard we present a model which is free from the coincidence problem and, at the same time, does the crossing of the phantom barrier ω = −1 at late time. Finally, we give additional comments on the non-predictive properties of scalar-field cosmological models with or without energy transfer.
