The classical double copy in maximally symmetric spacetimes
Mariana Carrillo-Gonzalez, Riccardo Penco, Mark Trodden
The classical double copy procedure relates classical asymptotically-flat gravitational field solutions to Yang-Mills and scalar field solutions living in Minkowski space. In this…
Finding structure in the dark: coupled dark energy, weak lensing, and the mildly nonlinear regime
V Miranda, Mariana Carrillo González, Elisabeth Krause +1
We reexamine interactions between the dark sectors of cosmology, with a focus on robust constraints that can be obtained using only mildly nonlinear scales. While it is well known…
Field Theories and Fluids for an Interacting Dark Sector
Mariana Carrillo Gonzalez, Mark Trodden
We consider the relationship between fluid models of an interacting dark sector, and the field theoretical models that underlie such descriptions. This question is particularly imp…
The WKB approximation and tunneling in theories with non-canonical kinetic terms
Mariana Carrillo Gonzalez, Ali Masoumi, Adam R. Solomon +1
Tunneling is a fascinating aspect of quantum mechanics that renders the local minima of a potential meta-stable, with important consequences for particle physics, for the early hot…
Baryogenesis via Dark Matter-Induced Symmetry Breaking in the Early Universe
Jeremy Sakstein, Mark Trodden
We put forward a new proposal for generating the baryon asymmetry of the universe by making use of the dynamics of a scalar field coupled to dark matter. High dark…
