Multioscillating black holes

A bstract We study rotating global AdS solutions in five-dimensional Einstein gravity coupled to a multiplet complex scalar within cohomogeneity-1 ansatz. The onset of the gravitational and field superradiant instabilities Myers-Perry-AdS black hole mark bifurcation points resonators hairy holes, respectively. These are subject other (gravitational or scalar) instability, result which contain both hair. have smooth zero-horizon limits that we call graviboson stars. In resonator solutions, multiple components with different frequencies excited, hence these multioscillating solutions. phase structure examined microcanonical ensemble, i.e. at fixed energy angular momenta. It is found entropy never largest among them. also find holes higher wavenumbers entropically dominant occupy more space than those lower wavenumbers.
