Small free field inflation in higher curvature gravity
Jose D. Edelstein, Robert B. Mann, David Vázquez Rodríguez +1
Within General Relativity, a minimally coupled scalar field governed by a quadratic potential is able to produce an accelerated expansion of the universe provided its value and exc…

Aspects of Geometric Inflation
Jose D. Edelstein, David Vázquez Rodríguez, Alejandro Vilar López
We revisit the recently proposed mechanism of Geometric Inflation. On general grounds, we show that obtaining the right amount of inflation demands an exceedingly large initial ene…

The first -correction to homogeneous Yang-Baxter deformations using
Riccardo Borsato, Alejandro Vilar López, Linus Wulff
We use the -covariant formulation of supergravity familiar from Double Field Theory to find the first -correction to (unimodular) homogeneous Yang-Baxter (YB) deformati…
