Black hole thermodynamics equations

WebThe differentiation of black hole mass in an extended phase space satisfies the first law of thermodynamics as follows [21] (6) d M = T d S + Φ d Q + V d P + A d λ, where Φ = Q / r h is being the electrostatic potential, S = π r h 2 is being the entropy and A = [ ln ( r h / λ)] / 2 is being the conjugate quantity, T is the Hawking temperature … Webof a black hole (the same-size black hole) used to scale the vacuum energy. Apart from the limitations of this argu-ment [32], this is an attempt to propose a thermodynamic approach to reconcile quantum and gravity, resulting in an HDE model with appropriate behavior (see Ref. [29] and its citations). Because of the anonymous nature of DE ...

WebBlack hole thermodynamics has been proposed for many years since the entropy and temperature were found by Bekenstein and Hawking [ 1, 2 ], even getting many interesting results, like the four laws of black hole thermodynamics. It established the connection between the gravity and thermodynamics. WebBarrow proposed that the area law of the entropy associated with a horizon might receive a “fractal correction” due to quantum gravitational effects—in place of S∝A, we have instead S∝A1+δ/2, where 0⩽δ⩽1 measures the deviation from the standard area telli imbiss aarau https://southwestribcentre.com
