Abstract
We prove the existence and nonexistence of L2(R3)-normalized solutions of two coupled semi-relativistic Hartree equations, which arise from the studies of boson stars and multi-component Bose–Einstein condensates. Under certain condition on the strength of intra-specie and inter-specie interactions, by proving some delicate energy estimates, we give a precise description on the concentration behavior of ground state solutions of the system. Furthermore, an optimal blowing up rate for the ground state solutions of the system is also proved.
