The Schwarzschild black hole in f(R) exist superradiation phenomenon

For the relationship of the limit $y$ of the incident particle under the superradiance of the preset boundary (${\mu} = {y}{\omega}$)and the limit $y$ of the incident particle under the Hawking radiation of the preset boundary (${y}{\mu} ={\omega}$),we find the relationship between black hole thermodynamics and superradiation, and use boundary conditions to establish the relationship between y and R. We find that the black hole energy and momentum tensor is transformed into an effective potential. When the effective potential has a potential barrier, then we know that the Schwarzschild black hole in f(R) exist superradiation phenomenon.
