【摘要】 文章对作为暗能量候选者之一的Quintessence场与物质的相互作用及其在宇宙学中的应用进行了研究,通过引入Quintessence与重子流的耦合合理地解释了重子与反重子的不对称性。另外还详细地计算了重子数等曲率扰动。更多还原

【Abstract】 Quintessence is a possible candidate for dark energy. In this paper we study the possibility of Quintessence interacting with the ordinary matter and its implications in baryogenesis. With a specific coupling of the Quintessence to the baryon fields, we will show that the baryon number asymmetry of the universe can be explained naturally. We will also in this paper study the isocur-vature perturbation of the baryon number in our model.更多还原
