A candidate for an UV completion: quadratic gravity in first order formalism
Enrique Alvarez, Jesus Anero, Sergio Gonzalez-Martin +1
We consider the most general action for gravity which is quadratic in curvature. In this case first order and second order formalisms are not equivalent. This framework is a good c…
Ghost-free higher derivative unimodular gravity
Enrique Alvarez, Sergio Gonzalez-Martin
The unimodular version of the ghost-free higher derivative gravity is obtained. It is the unimodular reduction of some particular lagrangians quadratic in curvature.
Do the gravitational corrections to the beta functions of the quartic and Yukawa couplings have an intrinsic physical meaning?
S. Gonzalez-Martin, C. P. Martin
We study the beta functions of the quartic and Yukawa couplings of General Relativity and Unimodular Gravity coupled to the and Yukawa theories with masses. We show that the…
Asymptotic solutions in asymptotic safety
Sergio Gonzalez-Martin, Tim R. Morris, Zoë H. Slade
We explain how to find the asymptotic form of fixed point solutions in functional truncations, in particular approximations. We find that quantum fluctuations do not decoupl…
