Free random variables and molecular spectra. (English) Zbl 1024.60023
Summary: We briefly review the method of free random variables and its relation to random matrices. To demonstrate use of the approach, we apply the formalism to study the effect of static disorder on the density of states in a model Hamiltonian system.
