Abstract
We review the Bekenstein bound for thermodynamic entropy, and its derivation from arguments of black hole physics. Then we consider different generalized entropies as Tsallis-Cirto, Barrow, Tsallis-Jensen, and Renyi entropies. Thus, we establish new quantitative bounds on such entropies, arriving in this way to new formulations of the Bekenstein bound itself. We also briefly comment on the connections between the Bekenstein bound and the (generalized) uncertainty principle.
Biography
Dr. Fabio Scardigli currently works at the Department of Mathematics of Politecnico of Milano, Italy. He earned his PhD in Theoretical Physics at the University of Bern (Switzerland), supervised by Petr Hajicek, with a dissertation in General Relativity. Dr. Scardigli has held a number of research fellow positions: at CENTRA of Instituto Superior Tecnico in Lisbon, with Jose' Lemos; at the Yukawa Institute for Theoretical Physics in Kyoto, with Misao Sasaki; and at LeCosPA, collaborating with Pisin Chen. He authored over 73 scientific articles, and two books. His research interests focus on theories of gravity, generalized uncertainty principles applied to cosmology and black holes, foundations of quantum mechanics, and planetary systems.
