Torsional pseudo-inflation beyond Einstein-Cartan
Fernando Izaurieta, Samuel Lepe, Cristian Quinzacara
Torsion entered early-universe cosmology twice: through the nonsingular Einstein--Cartan bounce, where the quantum spin of fermions halts the contraction, and through the proposal…
How greedy is the Universe? An entropy ledger and a causal envelope for early black hole growth
Fernando Izaurieta, Cristian Quinzacara, Omar Valdivia
The entropy of the observable Universe is dominated, by fifteen orders of magnitude, by the horizons of supermassive black holes, and gravitational collapse into black holes has of…
No late-time role for adiabatic torsion: a no-go result for Hubble-cutoff holographic dark energy in Einstein--Cartan cosmology
Fernando Izaurieta, Samuel Lepe, Cristian Quinzacara
In Friedmann cosmology with Einstein--Cartan torsion, the homogeneous torsion mode compatible with a separately conserved matter sector scales as and enters the F…
A Geometric Action Principle for Unification of Yang-Mills Fields, Gravity and Matter Fermions
Pedro D. Alvarez, Fernando Izaurieta, Cristian Quinzacara
A single geometric action, constructed as a linear combination of a restricted six-dimensional family of Clifford-generated invariant terms, simultaneously generates the gravitatio…
(Quasi-)normal modes of rotating black holes and new solitons in Einstein-Gauss-Bonnet
Lilianne Tapia, Monserrat Aguayo, Andrés Anabalón +5
In this paper, we analyze the scalar field (quasi-)normal modes of recently derived rotating black holes within the framework of Einstein-Gauss-Bonnet theory at the Chern-Simons po…
Gravitational Faraday Effect induced by Dark Matter Spin
F. Barriga, F. Izaurieta, S. Lepe +4
We show that the spin of dark matter induces a gravitational analog of the electromagnetic Faraday effect, where the polarization of gravitational waves undergoes a rotation as the…
