Formation of solitons and their transitions in scalar-field dark matter models with a non-polynomial self-interaction potential
A saturating scalar self-interaction lets dark matter halos form Thomas-Fermi solitons, fuzzy solitons, or transitions between them, with even subdominant interactions seeding fuzzy solitons.
