Abelian-Higgs strings in Rastall gravity
Eugenio R. Bezerra de Mello, Julio C. Fabris, Betti Hartmann
In this paper we analyze Abelian-Higgs strings in a phenomenological model that takes quantum effects in curved space-time into account. This model, first introduced by Rastall, ca…
Self-interacting boson stars with a single Killing vector field in Anti-de Sitter
Yves Brihaye, Betti Hartmann, Jürgen Riedel
We construct rotating boson stars in (4+1)-dimensional asymptotically Anti-de Sitter space-time (aAdS) with two equal angular momenta that are composed out of a massive and self-in…
Charged Q-balls and boson stars and dynamics of charged test particles
Yves Brihaye, Valeria Diemer, Betti Hartmann
We construct electrically charged Q-balls and boson stars in a model with a scalar self-interaction potential resulting from gauge mediated supersymmetry breaking. We discuss the p…
