When AdS Grows Hair: Boson Stars, Black Holes, and Double-Trace Deformations
Oscar J. C. Dias, David Sola Gil, Jorge E. Santos
We analyse three-dimensional Einstein gravity coupled to a massive complex scalar field with double-trace boundary conditions. Using high-precision spectral methods, we construct r…

Double-trace instability of BTZ black holes
Oscar J. C. Dias, David Sola Gil, Jorge E. Santos
We perform a comprehensive study of the linear stability of rotating BTZ black holes under massive scalar field perturbations with double-trace boundary conditions. While BTZ black…
