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… 



Reissner-Nordström black holes supporting nonminimally coupled massive scalar field configurations

It has recently been demonstrated that static spatially regular scalar fields, which are nonminimally coupled to the electromagnetic field of a charged central black hole, can be supported in the

Superradiation of Dirac particles in KN ds black hole

In this article, we process the approximate wave function of the Dirac particle outside the horizon of the KN ds black hole to obtain V, and then derive V (including real and imaginary parts). We

Horizon thermodynamics in f(R) theory

We investigate whether the new horizon first law proposed recently still work in f(R) theory. We identify the entropy and the energy of black hole as quantities proportional to the corresponding

Entropy and Energy of Static Spherically Symmetric Black Hole in f(R) Theory

We consider the new horizon first law in f ( R ) theory. We derive the general formulas to computed the entropy and energy for static spherically symmetric black hole. For applications, some

Superradiant stability of the Kerr black hole

Algebraic methods are used to prove the stability of the Kerr black hole against certain scalar perturbations.

The Thermal Entropy Density of Spacetime

The thermal entropy density of any arbitrary spacetime without assuming a temperature or a horizon is obtained and the results confirm that there is a profound connection between gravity and thermodynamics.
