AdS boson stars in string theory

Abstract

Boson stars are stationary soliton-like gravitational configurations supported by a complex scalar field charged under the global $U(1)$ symmetry. We discuss properties of boson stars in type IIB supergravity approximation to string theory. A notable difference is that in supergravity models the global symmetry of the complex scalar field is gauged. We focus on global asymptotically $Ad{S}_5$ space-time, where the boson stars are expected to represent stable low-energy non-thermal excitations in holographically dual quiver conformal gauge theory.
