Abstract

摘要

Axions were originally suggested to solve the strong CP problem and ALPs generally exist in the string theory. We found that axions/ALPs can form Bose-Einstein condensation which differ them from fermionic dark matter. The long correlation length and high phase space density of axion/ALPs dark matter are very special and we will discuss the possible cosmological and astronomical implications due to these special properties.
