Setting the physical scale of dimensional reduction in causal dynamical triangulations
Joshua H. Cooperman, Manuchehr Dorghabekov
Within the causal dynamical triangulations approach to the quantization of gravity, striking evidence has emerged for the dynamical reduction of spacetime dimension on sufficiently…
Scaling analyses of the spectral dimension in 3-dimensional causal dynamical triangulations
Joshua H. Cooperman
The spectral dimension measures the dimensionality of a space as witnessed by a diffusing random walker. Within the causal dynamical triangulations approach to the quantization of…
A second look at transition amplitudes in (2+1)-dimensional causal dynamical triangulations
Joshua H. Cooperman, Kyle Lee, Jonah M. Miller
Studying transition amplitudes in (2+1)-dimensional causal dynamical triangulations, Cooperman and Miller discovered speculative evidence for Lorentzian quantum geometries emerging…
Comments on "Searching for a continuum limit in CDT quantum gravity"
Joshua H. Cooperman
To facilitate the search for a continuum limit of causal dynamical triangulations, Ambjorn, Coumbe, Gizbert-Studnicki, and Jurkiewicz recently reported measurements of the lattice…
Renormalization of lattice-regularized quantum gravity models I. General considerations
Joshua H. Cooperman
Lattice regularization is a standard technique for the nonperturbative definition of a quantum theory of fields. Several approaches to the construction of a quantum theory of gravi…
Making the case for causal dynamical triangulations
Joshua H. Cooperman
The aim of the causal dynamical triangulations approach is to define nonperturbatively a quantum theory of gravity as the continuum limit of a lattice-regularized model of dynamica…
Scale-dependent homogeneity measures for causal dynamical triangulations
Joshua H. Cooperman
I propose two scale-dependent measures of the homogeneity of the quantum geometry determined by an ensemble of causal triangulations. The first measure is volumetric, probing the g…
Renormalization of lattice-regularized quantum gravity models II. The case of causal dynamical triangulations
Joshua H. Cooperman
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 renormaliz…
A first look at transition amplitudes in (2+1)-dimensional causal dynamical triangulations
Joshua H. Cooperman, Jonah Miller
We study a lattice regularization of the gravitational path integral--causal dynamical triangulations--for (2+1)-dimensional Einstein gravity with positive cosmological constant in…
Renormalization of Entanglement Entropy and the Gravitational Effective Action
Joshua H. Cooperman, Markus A. Luty
The entanglement entropy associated with a spatial boundary in quantum field theory is UV divergent, with the leading term proportional to the area of the boundary. For a class of…
Quantizing Horava-Lifshitz Gravity via Causal Dynamical Triangulations
Christian Anderson, Steven Carlip, Joshua H. Cooperman +3
We extend the discrete Regge action of causal dynamical triangulations to include discrete versions of the curvature squared terms appearing in the continuum action of (2+1)-dimens…
Rescuing the Born Rule for Quantum Cosmology
Joshua H. Cooperman
Page has recently argued that the Born rule does not suffice for computing all probabilities in quantum cosmology. He further asserts that the Born rule's failure gives rise to the…
