Black bounce as a quantum correction from string T-duality: Thermodynamics, energy conditions, and observational imprints from EHT
G. Alencar, T. M. Crispim, Diego Sáez-Chillón Gómez +1
Motivated by quantum gravity effects suggested by string theory, we investigate gravitational configurations sourced by an effective energy density inspired by T-duality. This dens…
General spherically symmetric black bounces within non-linear electrodynamics
G. Alencar, Albert Duran-Cabacés, Diego Rubiera-Garcia +1
Over the last years, the search of new regular black bounce solutions has drawn a lot of attentional over the international community working in gravitation. Indeed, in the era of…
Boundary terms and on-shell action in Ricci-based gravity theories: the Hamiltonian formulation
Gerardo Mora-Pérez, Gonzalo J. Olmo, Diego Rubiera-Garcia +1
Considering the so-called Ricci-based gravity theories, a family of extensions of General Relativity whose action is given by a non-linear function of contractions and products of…
f(R, T, R_μνT^μν) gravity phenomenology and ΛCDM universe
Sergei D. Odintsov, Diego Sáez-Gómez
We propose general f(R,T,R_{μν}T^{μν}) theory as generalization of covariant Horava-like gravity with dynamical Lorentz symmetry breaking. FRLW cosmological dynamics for several ve…
Dynamics of scalar perturbations in f(R,T) gravity
F. G. Alvarenga, A. de la Cruz-Dombriz, M. J. S. Houndjo +2
In the context of f(R,T) theories of gravity, we study the evolution of scalar cosmological perturbations in the metric formalism. According to restrictions on the background evolu…
U(1) Invariant F(R) Horava-Lifshitz Gravity
Josef Kluson, Shin'ichi Nojiri, Sergei D. Odintsov +1
This paper is devoted to the study of various aspects of projectable F(R) Horava-Lifshitz (HL) gravity. We show that some versions of F(R) HL gravity may have stable de Sitter solu…
