In our work, we compute the 4-dimensional Einstein–Gauss–Bonnet gravity black hole solution by applying the Newman–Janis approach and also examine the Hawking temperature. The generalized uncertainty principle (GUP) is applied to compute the Lagrangian field equation and by using the semi-classical phenomenon, we analyze the modified Hawking temperature. By taking into account the graphical analysis, we check the stable conditions of the black hole with the influence of rotation parameter, charged parameter and quantum gravity parameter. Furthermore, we compute the logarithmic entropy corrections in the background of corrected temperature and standard entropy for corresponding black hole. We study the behavior of different thermodynamics quantities like Helmholtz free energy, internal energy, Gibbs free energy and heat capacity under these fluctuations. In our analysis, we note that these corrections enhance the stability of this system, so, under the effects of these corrections, the considered geometry becomes more stable. [ABSTRACT FROM AUTHOR]

In this paper, we compute the Hawking temperature by applying quantum tunneling approach for the Horndeski like black holes. We utilize the semi-classical phenomenon and WKB approximation to the Lagrangian field equation involving generalized uncertainty principle (GUP) and compute the tunneling rate as well as Hawking temperature. For the zero gravity parameter, we obtain results consistent without correction parameter or original tunneling. Moreover, we study the thermal fluctuations of the considered geometry and examine the stable state of the system by heat capacity technique. We also investigate the behavior of thermodynamic quantities under the influence of thermal fluctuations. We observe from the graphical analysis, the corresponding system is thermodynamically stable with these correction terms. • We compute the Hawking temperature by applying the quantum tunneling approach for the Horndeski-like black holes. • We utilize the semi-classical phenomenon and WKB approximation to the Lagrangian field equation. • For the zero gravity parameter, we see results consistent without the correction parameter. • We studied thermodynamics and thermal fluctuations of the considered geometry. • It is noted that the considered system is thermodynamically stable under these correction terms.

We use the Parikh-Wilczek method to study the tunneling radiation from the event horizon of a charged AdS black hole in $f(R)$ gravity. The emission rate of a particle is calculated. The emission spectrum deviates from the pure thermal spectrum but consists with an underlying unitary theory. The emission rate of massive particles takes the same functional form as that of massless particles. Contradictory but interesting phenomenon is discovered. The expression of the emission rate for a black hole in $f(R)$ gravity differs from that for a black hole in Einstein gravity, if the area-law of the black hole entropy is insisted on. Conversely, based on abandoning the area-law and admitting the conventional tunneling rate, we obtain the expressions of the entropy and the first law of thermodynamics for the $f(R)$ gravity black hole, which is in accordance with the early results. So the research of tunneling radiation in this paper may serve as a new perspective of understanding the thermodynamics of black holes in $f(R)$ gravity. [ABSTRACT FROM AUTHOR]

Although the tunneling approach is fully established for black hole radiation, much work has been done to support the extension of this approach to more general settings. In this paper the Parikh–Kraus–Wilczeck tunneling proposal of black hole tunneling radiation is considered. The thermodynamics of the higher dimensional Schwarzschild black hole is studied based on the generalized uncertainty principle (GUP) and the modified dispersion relation (MDR) analysis, separately. It is shown that entropy and the rate of the higher dimensional Schwarzschild black hole tunneling radiation receive some corrections. The leading-order corrections does not contain the logarithmic term of the entropy, if the dimensions of the space–time is an odd number. Through the comparison, it is found that the results of these two alternative approaches are identical if one uses the suitable expansion coefficients. [ABSTRACT FROM AUTHOR]

lthough the tunneling approach is well established for black hole's radiation, much works have been done to support the extension of this approach to more general settings. In This letter the Parikh-Kraus-Wilczek tunneling proposal of black hole's tunneling radiation has been considered. The de Sitter-Schwarzschild black hole's thermodynamics has been studied based on both, the generalized uncertainty principle and the modified dispersion relations analysis. It is shown that entropy, temperature and the original Parikh-Kraus-Wilczek calculations of the black hole's tunneling probability receive new corrections. The results of these two alternative approaches are identical if one uses the suitable expansion coefficients. [ABSTRACT FROM AUTHOR]
