New Formulation of the First Law of Black Hole Thermodynamics: A Stringy Analogy
S. Q. Wu
We consider the first laws of thermodynamics for a pair of systems made up of the two horizons of a Kerr-Newman black hole. These two systems are constructed in such a way that we…
Quantum Thermal Effect of Dirac Particles in a Non-uniformly Rectilinearly Accelerating Black Hole with Electronic Charge, Magnetic Charge and Cosmological Constant
S. Q. Wu, X. Cai
The Hawking radiation of Dirac particles in an arbitrarily rectilinearly accelerating Kinnersley black hole with electro-magnetic charge and cosmological constant is investigated b…
Hawking Radiation of Photons in a Vaidya-de Sitter Black Hole
S. Q. Wu, X. Cai
Hawking evaporation of photons in a Vaidya-de Sitter black hole is investigated by using the method of generalized tortoise coordinate transformation. Both the location and the tem…
Extra Spin-Rotation Coupling Effect in a Radiating Kerr Space-time
S. Q. Wu, X. Cai
Source-less wave equations are derived for massless scalar, neutrino and electromagnetic perturbations of a radiating Kerr space-time, and the Hawking radiation of massless particl…
Asymmetry of Hawking Radiation of Dirac Particles in a Charged Vaidya - de Sitter Black Hole
S. Q. Wu, X. Cai
The Hawking radiation of Dirac particles in a charged Vaidya - de Sitter black hole is investigated by using the method of generalized tortoise coordinate transformation. It is sho…
Generalized Laws of Black Hole Thermodynamics and Quantum Conservation Laws on Hawking Radiation Process
S. Q. Wu, X. Cai
Four classical laws of black hole thermodynamics are extended from exterior (event) horizon to interior (Cauchy) horizon. Especially, the first law of classical thermodynamics for…
