Description
Causal Dynamical Triangulations (CDT) is a background
independent approach to quantum gravity which introduces a
lattice regularization.
In this talk, we will describe computational methods of CDT,
particularly the Monte Carlo algorithm.
We will discuss what we can measure and, based on that, what
phase structure we observe.
We will present how to extract the effective action for a
scale factor, which is of physical interest,
using the covariance matrix method and the transfer matrix
method.
Finally, we will highlight some aspects of code
parallelization with the aim at improving the performance
and speeding up the thermalization stage.
