New constraints on modified gravity with dimension-six operators from gravitational waves
Justo López-Sarrión, Carlos M. Reyes, César Riquelme +1
The present article deals with gravitational-wave propagation affected by higher-derivative terms that break spacetime symmetries. Two dimension-6 contributions of the gravitationa…
BBN bounds on neutrinophilic ultralight Dark Matter
Toni Bertólez-Martínez, Justo López-Sarrión, Jordi Salvado
The high densities in the early Universe provide a unique laboratory to constrain couplings between feebly interacting particles, such as dark matter and neutrinos. In this article…
Integrability meets the charged relativistic particle
Francisco Correa, Justo López-Sarrión
We notice an analogy between the motion of a relativistic particle with external homogeneous and time-dependent electromagnetic fields and the Dik'ii-Eilenberger equation for the B…
Chiral bosonization for non-commutative fields
Ashok Das, Jorge Gamboa, Fernando Méndez +1
A model of chiral bosons on a non-commutative field space is constructed and new generalized bosonization (fermionization) rules for these fields are given. The conformal structure…
