Ultraviolet Closure in Asymptotically Weyl-Invariant Gravity
Daniel Coumbe
We investigate asymptotically Weyl-invariant gravity (AWIG) in the Palatini formulation, defined by an exponent n that interpolates between an Einstein-like infrared regime, where…
A Falsifiable Alternative to General Relativity
Daniel Coumbe, Aria Rahmaty
Asymptotically Weyl-invariant gravity (AWIG) is further developed within the Palatini formalism as a power-counting renormalizable alternative to general relativity (GR). An expres…
Is Asymptotically Weyl-Invariant Gravity Viable?
Daniel Coumbe
We explore the cosmological viability of a theory of gravity defined by the Lagrangian in the Palatini formalism, where $n\…
Asymptotically Weyl-Invariant Gravity
Daniel Coumbe
We propose a novel theory of gravity that by construction is renormalizable, evades Ostragadsky's no-go theorem, is locally scale-invariant in the high-energy limit, and equivalent…
Critical Phenomena in Causal Dynamical Triangulations
J. Ambjorn, D. Coumbe, J. Gizbert-Studnicki +2
Four-dimensional CDT (causal dynamical triangulations) is a lattice theory of geometries which one might use in an attempt to define quantum gravity non-perturbatively, following t…
A note on conformal symmetry
D. N. Coumbe
We investigate a conformal-like transformation for which the spacetime interval is invariant.
