Physical nonviability of $f (Q)$ in the scalar-tensor representation

Jose Beltrán Jiménez, Alejandro Jiménez Cano, Tomi S. Koivisto

We show the known pathological character of $f (Q)$ gravity in its scalar-tensor representation.

A solid unification of the dark sector

Jose Beltrán Jiménez, María Pérez Garrote, Florencia A. Teppa Pannia +1

We construct a unified description of dark matter and dark energy in terms of a single dark component that behaves as a pressureless fluid in the early Universe and undergoes a tra…
