各位老师和同学：
兹邀请蔡一夫于5月29上午10:00（周二）来我实验室做学术报告，请相互转告并准时参加。
报告地点：三楼会议室
报告题目：Brief Review of Quintom Cosmology
报告摘要：his is a review talk on Quintom cosmology. First, I will briefly review the current study of dark energy physics. Then, I will focus on a class of dynamical dark energy models, dubbed Quintom. Its basic feature is that the equation of state is allowed to cross the cosmological constant boundary. I will introduce the theoretical foundation, a No-Go theorem for dynamical dark energy models to realize Quintom scenario. According to this No-Go theorem, we will study the cosmological implications and observational signatures of Quintom cosmology from the point of view of effective field description. Especially, the application of Quintom scenario in early universe implies a nonsingular bouncing solution. I will also talk about the consturction of a realistic cosmological bouncing model which can produce nearly scale-invariant primordial power spectrum in this scenario. Also I will talk about the Non-Gaussianities of this type of bounce cosmologies. Its reheating theory and isocurvature perturbations will be mentioned as well.
