Jacobson's thermodynamic approach to classical gravity applied to non-Riemannian geometries: remarks on the simplicity of Nature
Jhan N. Martinez, Jose F. Rodriguez-Ruiz, Yeinzon Rodriguez
Three decades ago, Ted Jacobson surprised us with a very appealing approach to classical gravity. According to him, the gravitational field equations are the consequence of the fir…

Dynamical Shortcomings in the Generalized SU(2) Proca Theory: Challenges for Cosmic Acceleration
Santiago Garcia-Serna, J. Bayron Orjuela-Quintana, Yeinzon Rodriguez +2
The Generalized SU(2) Proca (GSU2P) theory has recently garnered attention for its potential to describe key phases of cosmic evolution, including primordial inflation and late-tim…

Neutron stars in the generalized SU(2) Proca theory
Jhan N. Martinez, Jose F. Rodriguez, Laura M. Becerra +2
The generalized SU(2) Proca theory is a vector-tensor modified gravity theory characterized by an action that remains invariant under both diffeomorphisms and global internal trans…
