Considerations on Quantum Gravity Phenomenology [PDF]
Universe 2021, 7(11), 439, 2021 I describe two phenomenological windows on quantum gravity that seem promising to me. I argue that we already have important empirical inputs that should orient research in quantum gravity.

KPZ Formulas for Weyl-Invariant Induced Gravity and Topologically Massive Gravity [PDF]
Nucl.Phys.Proc.Suppl. 57 (1997) 276-279, 1997 I discuss the applicability in Weyl-invariant induced gravity and topologically massive gravity of certain formulas originally derived by Knizhnik, Polyakov, and Zamolodchikov in the context of diffeomorphism-invariant induced gravity.

Quantum gravity, fakeons and microcausality [PDF]
Journal of High Energy Physics, 2018 A bstractWe investigate the properties of fakeons in quantum gravity at one loop. The theory is described by a graviton multiplet, which contains the fluctuation hμν of the metric, a massive scalar ϕ and the spin-2 fakeon χμν .

The information metric on the moduli space of instantons with global symmetries
Physics Letters B, 2016 In this note we revisit Hitchin's prescription [1] of the Fisher metric as a natural measure on the moduli space of instantons that encodes the space–time symmetries of a classical field theory. Motivated by the idea of the moduli space of supersymmetric

International Journal of Modern Physics D, 2014 This paper presents an "in-a-nutshell" yet self-contained introductory review on loop quantum gravity (LQG) — a background-independent, nonperturbative approach to a consistent quantum theory of gravity. Instead of rigorous and systematic derivations, it aims to provide a general picture of LQG, placing emphasis on the fundamental ideas and their ...

Mass Difference for Charged Quarks from Asymptotically Safe Quantum Gravity. [PDF]
Physical Review Letters, 2018 We propose a scenario to retrodict the top and bottom mass and the Abelian gauge coupling from first principles in a microscopic model including quantum gravity.

Towards the map of quantum gravity [PDF]
, 2018 In this paper we point out some possible links between different approaches to quantum gravity and theories of the Planck scale physics. In particular, connections between Loop Quantum Gravity, Causal Dynamical Triangulations, Ho\v{r}ava-Lifshitz gravity,
