How Far Can Vierbeins Simplify Gravity?
Boris Latosh
We construct a classical formulation of gravity in terms of the vierbein that makes the Hilbert action polynomial in gravitational perturbations and identify some matter models tha…
Robustness of Starobinsky inflation in a minimal two-field scalar-tensor completion
Boris Latosh
We investigate whether the Starobinsky inflation remains robust after including a minimal scalar extension motivated by the one-loop effective action of scalar-tensor gravity. We n…
