AdS solitons with conformal scalar hair    [PDF]

Yves Brihaye, Betti Hartmann, Sardor Tojiev
We study spherically symmetric soliton solutions in a model with a conformally coupled scalar field as well as in full conformal gravity. We observe that a new type of limiting behaviour appears for particular choices of the self-coupling of the scalar field, i.e. the solitons interpolate smoothly between the Anti-de Sitter vacuum and an uncharged configuration. Furthermore, within conformal gravity the qualitative pattern of solutions does not seem to change when varying the U(1) gauge coupling - contrary to the Einstein-Hilbert case.
