报告摘要:
We report a new black hole scalarization mechanism and disclose novel dynamical critical phenomena in the process of the nonlinear accretion of the scalar field into black holes. The accretion process can transform a seed black hole into a final scalarized or bald black hole, depending on the initial parameter of the scalar field. There is a critical parameter and near it all intermediate solutions are attracted to a critical solution and stay there for a long time. At late times, the solutions evolve into bald/scalarized black holes for subcritical/supercritical cases. The final masses of the resulting scalarized/bald black holes satisfy a power-law.
