Computer Simulations of Causal Sets
L Glaser
This review introduces Markov Chain Monte Carlo simulations in causal set theory, with a focus on the study of the 2d orders. It will first introduce the Benincasa-Dowker action on…
Phase transitions in 2d orders coupled to the Ising model
Lisa Glaser
The d orders are a sub class of causal sets, which is especially amenable to computer simulations. Past work has shown that the d orders have a first order phase transition b…
Reconstructing manifolds from truncated spectral triples
Lisa Glaser, Abel B. Stern
We explore the geometric implications of introducing a spectral cut-off on Riemannian manifolds. This is naturally phrased in the framework of non-commutative geometry, where we wo…
Spectral estimators for finite non-commutative geometries
John W. Barrett, Paul Druce, Lisa Glaser
A finite non-commutative geometry consists of a fuzzy space together with a Dirac operator satisfying the axioms of a real spectral triple. This paper addreses the question of how…
Quantum Gravity on the computer: Impressions of a workshop
Lisa Glaser, Sebastian Steinhaus
Computer simulations allow us to explore non-perturbative phenomena in physics. This has the potential to help us understand quantum gravity. Finding a theory of quantum gravity is…
The Ising model coupled to 2d orders
Lisa Glaser
In this article we make first steps in coupling matter to causal set theory in the path integral. We explore the case of the Ising model coupled to the 2d discrete Einstein Hilbert…
