@article{East2017SuperradiantIA, title={Superradiant Instability and Backreaction of Massive Vector Fields around Kerr Black Holes.}, author={William E. East and Frans Pretorius}, journal={Physical review letters}, year={2017}, volume={119 4}, pages={ 041101 } }

We study the growth and saturation of the superradiant instability of a complex, massive vector (Proca) field as it extracts energy and angular momentum from a spinning black hole, using numerical solutions of the full Einstein-Proca equations. We concentrate on a rapidly spinning black hole (a=0.99) and the dominant m=1 azimuthal mode of the Proca field, with real and imaginary components of the field chosen to yield an axisymmetric stress-energy tensor and, hence, spacetime. We find that in…
