Spinning scalar solitons in anti-de Sitter spacetime

Understand

We present spinning Q-balls and boson stars in four dimensional anti-de Sitter spacetime.

• These are smooth, horizonless solutions for gravity coupled to a massive complex scalar field with a harmonic dependence on time and the azimuthal angle.
• Similar to the flat spacetime configurations, the angular momentum is quantized.
• We find that a class of solutions with a self-interaction potential has a limit corresponding to static solitons with axial symmetry only.
