O teorema de Noether e o momento angular das ondas gravitacionais
(Universidade Estadual Paulista (Unesp), 2022-03-08)
O Teorema de Noether é uma ferramenta poderosa dentro da mecânica analítica, esse consegue relacionar quantidades invariantes e simetrias dentro de um sistema físico. Todos os ferramentais advindos dos formalismos Lagrangianos ...
Supersymmetry in the non-commutative plane
(Academic Press Inc. Elsevier Science, 2005)
Magnetic mass in 4D AdS gravity
(AMER PHYSICAL SOC, 2016-04)
We provide a fully covariant expression for the diffeomorphic charge in four-dimensional anti-de Sitter gravity, when the Gauss-Bonnet and Pontryagin terms are added to the action. The couplings of these topological ...
Logarithmic correction to bh entropy as noether charge
(SPRINGER, 2010)
Einstein-Katz action, variational principle, Noether charges and the thermodynamics of AdS-black holes.
In this paper we describe 4-dimensional gravity coupled to scalar and Maxwell fields by the Einstein-Katz action, that is, the covariant version of the “Gamma-Gamma −Gamma-Gamma” part of the Hilbert action supplemented by ...
Cosmological horizons, Noether charges and entropy
(IOP Publishing, 2019-07-23)
It has recently been shown that, in the vicinity of their event horizons, black holes exhibit an infinite-dimensional symmetry. This symmetry captures relevant physical information about the black hole, and in particular ...
Conserved charges for gravity with locally anti-de sitter asymptotics
(2000)
A new formula for the conserved charges in 3+1 gravity for spacetimes with local anti-de Sitter asymptotic geometry is proposed. It is shown that requiring the action to have an extremum for this class of asymptotia sets ...
