The thermodynamic theory of black holes
WebJun 5, 2024 · The theory of relativity describes black holes as being spherical, smooth and simple. ... In this way, their mysterious thermodynamic properties have become more understandable: ... WebIn Sect. 3 the black hole thermodynamic and conserved quantities are calculated, and it is proved that, even in the presence of rainbow functions, the first law of black hole thermodynamics remains valid for both families of novel dilatonic BTZ black holes. Thermodynamic stability or phase transition of the black holes is explored in Sect. 4.

WebClassical black hole area theorem: δA ≥0 However, when a black hole is present, it really is physically meaningful to consider only the matter outside the black hole. But then, can decrease S by dropping matter into the black hole. So, can get δS < 0. Although classically A never decreases, it does decrease during the quantum particle ... WebIn this paper, we investigate the Ruppeiner thermodynamic geometry in the extended phase space of Reissner–Nordström (RN)-AdS black holes immersed in perfect fluid dark matter (PFDM) via P − V criticality. We first make a brief review on thermodynamics of this black hole, and further investigate the P − V criticality. We calculate the critical exponents near …
