Generalized Entropies and Black Hole Area Quantization from Landauer's Principle
Jorge Ananias Neto, Ronaldo Thibes
We investigate black hole area quantization by imposing Landauer's principle on the discrete entropy change between consecutive area levels. The elementary transition is identified…
Exploring modified Kaniadakis entropy: MOND-related theory, the Bekenstein bound conjecture, and Hawking evaporation within the Landauer principle
Gabriella V. Ambrósio, Michelly S. Andrade, Paulo R. F. Alves +3
We investigate the description of black-hole thermodynamics in terms of a recently proposed modified version for Kaniadakis entropy. We discuss the role of that proposal within the…
Note on an extended chiral bosons system contextualized in a modified gauge-unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +2
We analyze the Hamiltonian structure of an extended chiral bosons theory in which the self-dual constraint is introduced via a control -parameter. The system has two second-clas…
