The string swampland constraints require multi-field inflation
(Institute of Physics Publishing, 2019)
An important unsolved problem that affects practically all attempts to connect string theory to cosmology and phenomenology is how to distinguish effective field theories belonging to the string landscape from those that ...
Boltzmann hierarchies for self-interacting warm dark matter scenarios
(IOP Publishing, 2020-09)
We provide a general framework for self-interacting warm dark matter (WDM) in cosmological perturbations, by deriving from first principles a Boltzmann hierarchy which retains certain independence from a particular interaction ...

From inflation to recent cosmic acceleration: The fermionic Elko field driving the evolution of the universe
(2017-09-27)
In this paper we construct the complete evolution of the universe driven by the mass dimension one dark spinor called Elko, starting with inflation, passing by the matter dominated era and finishing with the recent accelerated ...
T -dual cosmological solutions in double field theory. II.
(2019-03-15)
In this paper we present cosmological solutions of double field theory in the supergravity frame and in the winding frame which are related via T-duality. In particular, we show that the solutions can be viewed without the ...
