摘要: Boson clouds around black holes exhibit interesting physical phenomena through the Penrose process of superradiance, leading to black-hole spin-down. Axionic are particular interest, since axion Compton wavelength could be comparable Schwarzschild radius, formation ``gravitational atoms'' with a nucleus. These collapse under certain conditions, ``Bosenova.'' We model dynamics such unstable boson by simple cellular automaton and show that it exhibits self-organized criticality. Our results suggest evolution Regge plane is due
