Disordered ensembles of random matrices
Abstract
It is shown that the families of generalized matrix ensembles recently considered which give rise to an orthogonal invariant stable L\'evy ensemble can be generated by the simple procedure of dividing Gaussian matrices by a random variable. The nonergodicity of this kind of disordered ensembles is investigated. It is shown that the same procedure applied to random graphs gives rise to a family that interpolates between the Erd\"os-Renyi and the scale free models.
