耦合暗能量:复标量场的动力学分析

Coupled dark energy: a dynamical analysis with complex scalar field

Ricardo C. G. Landim

摘要:

本文对暗物质与暗能量耦合的动力学问题进行了分析,其中考虑了复杂的标量场,并考虑了正压流体的存在。我们考虑三种暗能量候选者:精粹,幻影和快子。临界点的发现和他们的稳定性分析,导致三个宇宙时代(辐射,物质和暗能量),一个通用的潜力。这里提出的结果扩大了以前的分析中发现的文献。

英文摘要:

The dynamical analysis for coupled dark energy with dark matter is presented, where a complex scalar field is taken into account and it is considered in the presence of a barothropic fluid. We consider three dark energy candidates: quintessence, phantom and tachyon. The critical points are found and their stabilities analyzed, leading to the three cosmological eras (radiation, matter and dark energy), for a generic potential. The results presented here enlarge the previous analyses found in the literature.
