I will discuss the application of spectral analysis, i.e. analysis of the spectrum and eigenvectors of the Laplace-Beltrami operator, in the setting of the Monte-Carlo approach to Quantum Gravity called Causal Dynamical Triangulations (CDT). In particular, applying the method to the analysis of spatial slices shows that the different phases can be characterized by a new order parameter related...
