Wilson loops in CDT quantum gravity
J. Ambjorn, A. Goerlich, J. Jurkiewicz +1
By explicit construction, we show that one can in a simple way introduce and measure gravitational holonomies and Wilson loops in lattice formulations of nonperturbative quantum gr…
CDT and the Search for a Theory of Quantum Gravity
J. Ambjorn, A. Goerlich, J. Jurkiewicz +1
Causal Dynamical Triangulations provide a non-perturbative regularization of a theory of quantum gravity. We describe how this approach connects with the asymptotic safety program…
CDT---an Entropic Theory of Quantum Gravity
J. Ambjorn, A. Goerlich, J. Jurkiewicz +1
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 disc…
The Nonperturbative Quantum de Sitter Universe
J. Ambjorn, A. Goerlich, J. Jurkiewicz +1
The dynamical generation of a four-dimensional classical universe from nothing but fundamental quantum excitations at the Planck scale is a long-standing challenge to theoretical p…
Addition of Free Unitary Random Matrices
Andrzej T. Goerlich, Andrzej Jarosz
We consider a new class of non-Hermitian random matrices, namely the ones which have the form of sums of freely independent terms involving unitary matrices. To deal with them, we…
