Bose-Einstein Condensates in Charged Black-Hole Spacetimes
Elías Castellanos, Juan Carlos Degollado, Claus Lämmerzahl +2
We analyze Bose-Einstein condensates on three types of spherically symmetric and static charged black-hole spacetimes: The Reissner-Nordström spacetime, Hoffmann's Born-Infeld blac…
Quasistationary solutions of scalar fields around collapsing self-interacting boson stars
Alejandro Escorihuela-Tomàs, Nicolas Sanchis-Gual, Juan Carlos Degollado +1
There is increasing numerical evidence that scalar fields can form long-lived quasi-bound states around black holes. Recent perturbative and numerical relativity calculations have…
Self-gravitating black hole scalar wigs
Juan Barranco, Argelia Bernal, Juan Carlos Degollado +4
It has long been known that no static, spherically symmetric, asymptotically flat Klein-Gordon scalar field configuration surrounding a nonrotating black hole can exist in general…
Numerical evolutions of spherical Proca stars
Nicolas Sanchis-Gual, Carlos Herdeiro, Eugen Radu +2
Vector boson stars, or , have been recently obtained as fully non-linear numerical solutions of the Einstein-(complex)-Proca system. These are self-gravitatin…
