New topological observables in a model of Causal Dynamical Triangulations on a torus
Zbigniew Drogosz
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 topologica…
Scalar fields in Causal Dynamical Triangulations
Jan Ambjørn, Zbigniew Drogosz, Jakub Gizbert-Studnicki +3
A typical geometry extracted from the path integral of a quantum theory of gravity might be quite complicated in the UV region. Even if such a configuration is not physical, it may…
CDT Quantum Toroidal Spacetimes: An Overview
J. Ambjorn, Z. Drogosz, J. Gizbert-Studnicki +3
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…
Matter-driven change of spacetime topology
J. Ambjørn, Z. Drogosz, J. Gizbert-Studnicki +3
Using Monte-Carlo computer simulations, we study the impact of matter fields on the geometry of a typical quantum universe in the CDT model of lattice quantum gravity. The quantum…
Cosmic voids and filaments from quantum gravity
J. Ambjorn, Z. Drogosz, J. Gizbert-Studnicki +3
Using computer simulations we study the geometry of a typical quantum universe, i.e. the geometry one might expect before a possible period of inflation. We display it using coordi…
