We consider a new class of non–hermitian random matrices, namely the ones which have the form of sums of freely independent terms which involve unitary matrices. After deriving some general… (More)

We present an analytic method for calculating spectral densities of empirical covariance matrices for correlated data. In this approach the data is represented as a rectangular random matrix whose… (More)

The Causal Dynamical Triangulation model of quantum gravity (CDT) is a proposition to evaluate the path integral over space-time geometries using a lattice regularization with a discrete proper time… (More)
