Title: Impact of multi-stream dynamics on large-scale structure: a perturbative approach

Abstract: In standard picture of structure formation dominated by dark matter, the dark matter was initially cold, and hence followed the single-stream flow. While this is valid only during the early phase of structure formation, the single-stream flow is often invoked to analytically describe the large-scale structure based on perturbation theory (PT). In this talk, focusing on one-dimensonal cosmological case, I will discuss the impact of multi-stream flow, and present a new PT treatment that can describe the gravitational dynamics of cold dark matter beyond single-stream regime.
