Mini-twistors and the Cotton Double Copy
Mariana Carrillo González, William T. Emond, Nathan Moynihan +2
The double copy relates quantities in gauge, gravity and related theories. A well-known procedure for relating exact classical solutions is the Weyl double copy in four spacetime d…
Phase Transitions in de Sitter: Quantum Corrections
José Eliel Camargo-Molina, Mariana Carrillo González, Arttu Rajantie
We investigate the decay rate of a false vacuum state in de Sitter space at high Hubble rates, using two methods: the Hawking-Moss instanton method which is fully quantum mechanica…
Cotton Double Copy for Gravitational Waves
Mariana Carrillo González, Arshia Momeni, Justinas Rumbutis
We construct a double copy relation between the Cotton spinor and the dual field strength spinor of topologically massive theories, as the three-dimensional analogue of the Weyl do…
Double Copy for Massive Scalar Field Theories
Mariana Carrillo González, Qiuyue Liang, Mark Trodden
We explore extensions of the double copy to massive theories and find a new cubic theory with a local double copy. We consider the nonlinear sigma model and the special galileon th…
Massive Double Copy in the High-Energy Limit
Mariana Carrillo González, Arshia Momeni, Justinas Rumbutis
The exploration of the massive double copy is still in its infancy, and only a few examples in limited contexts are known. In this paper, we analyze the newly discovered double cop…
Cosmology and Signals of Light Pseudo-Dirac Dark Matter
Mariana Carrillo González, Natalia Toro
In this paper, we analyze the cosmological evolution, allowed parameter space, and observational prospects for a dark sector consisting of thermally produced pseudo-Dirac fermions…
Massive Double Copy in Three Spacetime Dimensions
Mariana Carrillo González, Arshia Momeni, Justinas Rumbutis
Recent explorations on how to construct a double copy of massive gauge fields have shown that, while any amplitude can be written in a form consistent with colour-kinematics dualit…
