The effective action in four-dimensional CDT
Jakub Gizbert-Studnicki
We present recent results concerning the measurement and analysis of the effective action in four-dimensional Causal Dynamical Triangulations. The action describes quantum fluctuat…
Recent results in CDT quantum gravity
Jan Ambjorn, Daniel Coumbe, Jakub Gizbert-Studnicki +1
We review some recent results from the causal dynamical triangulation (CDT) approach to quantum gravity. We review recent observations of dimensional reduction at a number of previ…
Exploring the new phase transition of CDT
D. N. Coumbe, J. Gizbert-Studnicki, J. Jurkiewicz
This work focuses on the newly discovered bifurcation phase transition of CDT quantum gravity. We define various order parameters and investigate which is most suitable to study th…
Signature Change of the Metric in CDT Quantum Gravity?
Jan Ambjørn, Daniel N. Coumbe, Jakub Gizbert-Studnicki +1
We study the effective transfer matrix within the semiclassical and bifurcation phases of CDT quantum gravity. We find that for sufficiently large lattice volumes the kinetic term…
