Simulating CDT quantum gravity
Joren Brunekreef, Andrzej Görlich, Renate Loll
We provide a hands-on introduction to Monte Carlo simulations in nonperturbative lattice quantum gravity, formulated in terms of Causal Dynamical Triangulations (CDT). We describe…
The phase structure and effective action of 3D CDT at higher spatial genus
Joren Brunekreef, Dániel Németh
We perform a detailed investigation of the phase structure and the semiclassical effective action of (2+1)-dimensional Causal Dynamical Triangulations (CDT) quantum gravity using c…
On the Nature of Spatial Universes in 3D Lorentzian Quantum Gravity
J. Brunekreef, R. Loll
Three-dimensional Lorentzian quantum gravity, expressed as the continuum limit of a nonperturbative sum over spacetimes, is tantalizingly close to being amenable to analytical meth…
Quantum Flatness in Two-Dimensional CDT Quantum Gravity
J. Brunekreef, R. Loll
Flatness -- the absence of spacetime curvature -- is a well-understood property of macroscopic, classical spacetimes in general relativity. The same cannot be said about the concep…
On the Semi-Classical Limit of Scalar Products of the XXZ Spin Chain
Yunfeng Jiang, Joren Brunekreef
We study the scalar products between Bethe states in the XXZ spin chain with anisotropy in the semi-classical limit where the length of the spin chain and the number of mag…
