In this paper we continue investigations concerning the physical nature of the black hole entropy.

As a first result, we obtain that, starting with a radiation field, we cannot exactly obtain the one-quarter factor in entropy area law. In the aforementioned framework, the correct black hole entropy is obtained only in the case where the internal temperature 𝑇𝑖, proportional to the Bekenstein-Hawking one, is such that 𝑇𝑖 → 0.

Abstract
In this paper we continue investigations concerning the physical nature of the black hole entropy. In particular, in order to depict massless excitations (gravitons) leading to the onequarter entropy area law, we use a mechanical statistical approach. As a first result, we obtain that, starting with a radiation field, we cannot exactly obtain the one-quarter factor in entropy area law. In the aforementioned framework, the correct black hole entropy is obtained only in the case where the internal temperature 𝑇𝑖, proportional to the Bekenstein-Hawking one, is such that 𝑇𝑖 → 0. As a consequence, according to other similar proposals in the literature, only a kind of Bose–Einstein condensate (BEC) can exactly support the black hole entropy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
