Coherent quantum hairy black holes from gravitational decoupling: regularity, geodesics, and scalar ringdown

Henrique Navarro, Roldao da Rocha

We construct a coherent-state quantum extension of gravitational-decoupling (GD) hairy black holes, in which the classical spacetime geometry emerges as the mean-field limit of a f…

Holographic information measures for spin- baryons in AdS/QCD

H. Almeida, R. da Rocha, P. H. O. Silva +1

Spin- baryon resonances are investigated within AdS/QCD, using Rarita-Schwinger fields. The differential configurational entropy (DCE) and differential configurational com…

Running Love Numbers of Charged Black Holes

Sergio Barbosa, Sylvain Fichet, Lucas de Souza

Loops of virtual particles from the vacuum of quantum field theory (QFT) render black holes tidally deformable. We compute the static tidal response of unspinning charged black hol…

The electromagnetic field in Poisson gauge theory: the groupoidal approach

Fabio Di Cosmo, Vladislav G. Kupriyanov, Patrizia Vitale

We consider the problem of defining the field strength of abelian potentials when the spacetime is a Poisson manifold, within the groupoidal approach. The natural definition in ter…

Symplectic realization of generalized Snyder-Poisson algebra

V. G. Kupriyanov, E. L. F. de Lima

We investigate Snyder space-time and its generalizations, including Yang and Snyder-de-Sitter spaces, which constitute manifestly Lorenz invariant noncommutative geometries. This w…

Confinement/deconfinement at low temperatures and rotation in the exact soft wall model

Octavio C. Junqueira, Roldao da Rocha

We study the effects of rotation on the confinement/deconfinement phase transition of strongly interacting matter, at low temperatures, in the soft wall AdS/QCD model at finite den…
