Ground states of a coupled pseudo-relativistic Hartree system: existence and concentration behavior

Abstract

This paper is concerned with the ground states of a coupled pseudo-relativistic Hartree system in ${\mathbb{R}}^3$ with trapping potentials, where the intraspecies and the interspecies interaction are both attractive. By investigating an associated constraint minimization problem, the existence and non-existence of ground states are classified completely. Under certain conditions on the trapping potentials, we present a precise analysis on the concentration behavior of the minimizers as the coupling coefficient goes to a critical value, where the minimizers blow up and the maximum point sequence concentrates at a global minima of the associated trapping potentials. We also identify an optimal blowing up rate under polynomial potentials by establishing some delicate estimates of energy functionals.
