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…
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…
