What if the Universe Expands Linearly? A Local General Relativity to Solve the “Zero Active Mass” Problem

open access: yesThe Astrophysical Journal
Modern cosmology presents important challenges such as the Hubble Tension, El Gordo’s collision, or the impossible galaxies ( z > 10). Slight modifications to the standard model propose new parameters (e.g., the early and dynamical dark energy).

The chiral torsional anomaly and the Nieh-Yan invariant with and without boundaries

open access: yesJournal of High Energy Physics
There exists a long-standing debate regarding the torsion contribution to the 4d chiral anomaly of a Dirac fermion. Central to this debate is the Nieh-Yan anomaly, which has been considered ill-defined and a regularization artifact.
