Induced Couplings and Causal Bounds from Nondegenerate Dirac Lagrangians
Marcelo Netz-Marzola, David Vasak, Vladimir Denk +2
The standard Dirac Lagrangian is linear in the field derivatives and therefore has a vanishing Hessian. We identify the minimal null deformations of this Lagrangian that make the c…
Tidal Forces in the Presence of Torsion and Nonmetricity
Armin van de Venn, Marcelo Netz-Marzola, David Vasak +1
This work investigates how torsion and nonmetricity modify tidal accelerations in metric-affine gravity. We derive a projected deviation equation that generalizes the standard geod…
Can Effects of a Generalized Uncertainty Principle Appear in Compact Stars?
João Gabriel Galli Gimenez, Dimiter Hadjimichef, Peter O. Hess +2
In the present contribution, a preliminary analysis of the effects of the Generalized Uncertainty Principle (GUP) with a minimum length, in the context of compact stars, is perform…
Cosmic inflation in an extended non-commutative foliated quantum gravity: the wave function of the universe
César A. Zen Vasconcellos, Peter O. Hess, José de Freitas Pacheco +8
We propose a novel extension to the recently developed non-commutative Riemannian foliated branch-cut quantum gravity (BCQG). Based on an extended Faddeev-Jackiw symplectic deforma…
