Composite localized field solutions in the Einstein-Yang-Mills theory in AdS spacetime — •Olga Kichakova¹, Jutta Kunz¹, Eugen Radu², and Yasha Shnir³ — ¹Oldenburg University — ²Aveiro University — ³JINR, Dubna

We construct new finite energy both regular and black hole solutions in Einstein-Yang-Mills-SU(2) theory. They are static, axially symmetric and approach at infinity the anti-de Sitter spacetime background. These configurations are characterized by a pair of integers (m,n), where m is related to the polar angle and n to the azimuthal angle, being related to the known flat space monopole-antimonopole chains and vortex rings. Generically, they describe composite configurations with several individual components, possesing a nonzero magnetic charge, even in the absence of a Higgs field. Such Yang-Mills configurations exist already in the probe limit, the AdS geometry supplying the attractive force needed to balance the repulsive force of Yang-Mills gauge interactions. The gravitating solutions are constructed by numerically solving the elliptic Einstein-DeTurck--Yang-Mills equations.
