Black holes with axion hair from cubic Riemann interactions
Roberto Casadio, Roldao da Rocha
An effective field theory (EFT) of gravity with a cubic Riemann invariant coupled to an axion-like field is investigated and shown to propagate no additional independent low-energy…
Topologically induced deformations of differential forms
J. M. Hoff da Silva, J. M. B. Matzenbacher, R. da Rocha
Motivated by deformations of spin structures and their geometric implications, we study a deformed exterior derivative, which is a third-order nilpotent operator. This higher-order…
Topological insulator realization induced by fermionic interaction through BF mediators
G. B. de Gracia, R. da Rocha, A. A. Nogueira +1
This paper demonstrates that ordinary fermions, interacting via a BF mediator, form a renormalized structure with non-trivial topological properties. We explore the analogy between…
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…
Gravitational decoupling and regular hairy black holes: Geodesic stability, quasinormal modes, and thermodynamic properties
R. C. de Paiva, K. S. Alves, R. T. Cavalcanti +1
The stability of geodesic orbits around a regular hairy black hole, in the gravitational decoupling setup, is investigated by employing Lyapunov exponents, which quantify the diver…
