This topical review gives a comprehensive overview and assessment of recent results in causal dynamical triangulations, a modern formulation of lattice gravity, whose aim is to obtain a theory of quantum gravity nonperturbatively from a scaling limit of the lattice-regularized theory. In this manifestly diffeomorphism-invariant approach one has direct, computational access to a Planckian spacetime regime, which is explored with the help of invariant quantum observables. During the last few… 
Renormalization in Quantum Theories of Geometry
A hallmark of non-perturbative theories of quantum gravity is the absence of a fixed background geometry, and therefore the absence in a Planckian regime of any notion of length or scale that is
CDT Quantum Toroidal Spacetimes: An Overview
Lattice formulations of gravity can be used to study non-perturbative aspects of quantum gravity. Causal Dynamical Triangulations (CDT) is a lattice model of gravity that has been used in this way.
Quantum Gravity: A Fluctuating Point of View
In this contribution, we discuss the asymptotic safety scenario for quantum gravity with a functional renormalization group approach that disentangles dynamical metric fluctuations from the
New topological observables in a model of Causal Dynamical Triangulations on a torus
The structure of simplicial manifolds in a model of Causal Dynamical Triangulations in 3+1 dimensions with the spatial topology of a 3-torus is analyzed with the help of topological observables, such
Geometric flux formula for the gravitational Wilson loop
Finding diffeomorphism-invariant observables to characterize the properties of gravity and spacetime at the Planck scale is essential for making progress in quantum gravity. The holonomy and Wilson
Matter-Driven Change of Spacetime Topology.
Using Monte Carlo computer simulations, the impact of matter fields on the geometry of a typical quantum universe in the causal dynamical triangulations (cdt) model of lattice quantum gravity is studied and a phase transition caused by the scalar field is observed.
Configuration space for quantum gravity in a locally regularized path integral
: We discuss some aspects of the metric configuration space in quantum gravity in the background field formalism. We give a necessary and sufficient condition for the parameterization of Euclidean metric
Curvature profiles for quantum gravity
Building on the recently introduced notion of quantum Ricci curvature and motivated by considerations in nonperturbative quantum gravity, we advocate a new, global observable for curved metric
Exploring black hole mechanics in cotangent bundle geometries
The classical and continuum limit of a quantum gravitational setting could lead, at mesoscopic regimes, to a very different notion of geometry with respect to the pseudo-Riemannian one of special and
Topology induced first-order phase transitions in lattice quantum gravity
Abstract Causal Dynamical Triangulations (CDT) is a lattice formulation of quantum gravity, suitable for Monte-Carlo simulations which have been used to study the phase diagram of the model. It has


Causal dynamical triangulations and the quest for quantum gravity
This work is the only approach to have demonstrated that a classical universe can be generated dynamically from Planckian quantum fluctuations, and allows for the explicit evaluation of expectation values of invariants characterizing the highly nonclassical, short-distance behaviour of spacetime.
Quantum spacetime, from a practitioner's point of view
We argue that theories of quantum gravity constructed with the help of (Causal) Dynamical Triangulations have given us the most informative, quantitative models to date of quantum spacetime. Most
On a renormalization group scheme for causal dynamical triangulations
The causal dynamical triangulations approach aims to construct a quantum theory of gravity as the continuum limit of a lattice-regularized model of dynamical geometry. A renormalization group
Renormalization of lattice-regularized quantum gravity models II. The case of causal dynamical triangulations
The causal dynamical triangulations approach aims to construct a quantum theory of gravity as the continuum limit of a lattice-regularized model of dynamical geometry. A renormalization group scheme|
Quantum Gravity via Causal Dynamical Triangulations
Causal dynamical triangulations (CDT ) represent a lattice regularization of the sum over spacetime histories, providing us with a nonperturbative formulation of quantum gravity. The ultraviolet
Spectral geometry as a probe of quantum spacetime
Employing standard results from spectral geometry, we provide strong evidence that in the classical limit the ground state of three-dimensional causal dynamical triangulations is de Sitter spacetime.
De Sitter Universe from Causal Dynamical Triangulations without Preferred Foliation
We present a detailed analysis of a recently introduced version of causal dynamical triangulations that does not rely on a distinguished time slicing. Focusing on the case of $2+1$ spacetime
CDT - an Entropic Theory of Quantum Gravity
In these lectures we describe how a theory of quantum gravity may be constructed in terms of a lattice formulation based on so-called causal dynamical triangulations (CDT). We discuss how the
