Monte Carlo renormalization of 2d simplicial quantum gravity coupled to Gaussian matter Original Research Article

We extend a recently proposed real-space renormalization group scheme for dynamical triangulations to situations where the lattice is coupled to continuous scalar fields. Using Monte Carlo simulations in combination with a linear, stochastic blocking scheme for the scalar fields we are able to determine the leading eigenvalues of the stability matrix with good accuracy both for cM = 1 and cM = 10 theories.
