We examine the general issue of whether a scale dependent cosmological constant can be consistent with general covariance, a problem that arises naturally in the treatment of quantum gravitation, where coupling constants generally run as a consequence of renormalization group effects. The issue is approached from several points of view, which include the manifestly covariant functional integral formulation, covariant continuum perturbation theory about two dimensions, the lattice formulation of… 

Quantum Gravity and Cosmological Density Perturbations

We explore the possible cosmological consequences of a running Newton's constant, G(2), as suggested by the non-trivial ultraviolet fixed point scenario for Einstein gravity with a cosmological

Asymptotic safety and the cosmological constant

A bstractWe study the non-perturbative renormalisation of quantum gravity in four dimensions. Taking care to disentangle physical degrees of freedom, we observe the topological nature of conformal

Cosmological constant problem and renormalized vacuum energy density in curved background

The current vacuum energy density observed as dark energy ρdark≃ 2.5×10−47 GeV4 is unacceptably small compared with any other scales. Therefore, we encounter serious fine-tuning problem and

Nonlocal gravity. Conceptual aspects and cosmological predictions

Even if the fundamental action of gravity is local, the corresponding quantum effective action, that includes the effect of quantum fluctuations, is a nonlocal object. These nonlocalities are well

Gravity in the infrared and effective nonlocal models

We provide a systematic and updated discussion of a research line carried out by our group over the last few years, in which gravity is modified at cosmological distances by the introduction of

Gravitational Fluctuations as an Alternative to Inflation III. Numerical Results

Power spectra play an important role in the theory of inflation, and their ability to reproduce current observational data to high accuracy is often considered a triumph of inflation, largely because

Essential Quantum Einstein Gravity

The non-perturbative renormalisation of quantum gravity is investigated allowing for the metric to be reparameterised along the RG flow, such that only the essential couplings constants are

Vacuum Condensate Picture of Quantum Gravity

The nonperturbative treatment of quantum gravity via the Regge–Wheeler lattice path integral formulation reveals the existence of a new phase involving a nontrivial gravitational vacuum condensate, and a new set of scaling exponents characterizing both the running of G and the long-distance behavior of invariant correlation functions.

Cosmic eggs to relax the cosmological constant

In theories with extra dimensions, the cosmological hierarchy problem can be thought of as the unnaturally large radius of the observable universe in Kaluza-Klein units. We sketch a dynamical

Graviton-mediated scattering amplitudes from the quantum effective action

We employ the curvature expansion of the quantum effective action for gravity-matter systems to construct graviton-mediated scattering amplitudes for non-minimally coupled scalar fields in a



Cosmological density perturbations with a scale-dependent Newton’s constant G

We explore possible cosmological consequences of a running Newton's constant $G(\ensuremath{\square})$, as suggested by the nontrivial ultraviolet fixed point scenario in the quantum field-theoretic

Renormalization group running of Newton's constant G : The static isotropic case

Corrections are computed to the classical static isotropic solution of general relativity, arising from non-perturbative quantum gravity effects. A slow rise of the effective gravitational coupling

Scale-Dependent Newton's Constant G in the Conformal Newtonian Gauge

In classical gravity deviations from the predictions of the Einstein theory are often discussed within the framework of the conformal Newtonian gauge, where scalar perturbations are described by two

Nonlocal effective gravitational field equations and the running of Newton's constant G

Non-perturbative studies of quantum gravity have recently suggested the possibility that the strength of gravitational interactions might slowly increase with distance. Here a set of generally

Cosmological and astrophysical tests of quantum gravity

Physics in the vicinity of an ultraviolet stable fixed point of a quantum field theory is parametrized by a renormalization group invariant macroscopic length scale, the correlation length $\xi,$

Gravitational Wilson loop in discrete quantum gravity

Results for the gravitational Wilson loop, in particular the area law for large loops in the strong coupling region, and the argument for an effective positive cosmological constant, discussed in a
