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…
Modified gauge unfixing formalism and gauge symmetries in the non-commutative chiral bosons theory
Cleber N. Costa, Gabriella V. Ambrósio, Paulo R. F. Alves +2
We use the gauge unfixing (GU) formalism framework in a two dimensional noncommutative chiral bosons (NCCB) model to disclose new hidden symmetries. That amounts to converting a se…
Restoring the gauge invariance in non-Abelian second-class theories
Paulo R. F. Alves, Cleber N. Costa, D. Fiorentini +3
In this paper, we propose a generalization of an improved gauge unfixing formalism in order to generate gauge symmetries in the non-Abelian valued systems. This generalization disp…
Revealing hidden symmetries and gauge invariance of the massive Carroll-Field-Jackiw model
Paulo R. F. Alves, Cleber N. Costa, Everton M. C. Abreu +2
In this paper we have analyzed the improved version of the Gauge Unfixing (GU) formalism of the massive Carroll-Field-Jackiw model, which breaks both the Lorentz and gauge invarian…
