Green’s function formalism for highly correlated systems

Green’s function formalism for highly correlated systems

We present the Composite Operator Method (COM) as a modern approach to the study of strongly correlated electronic systems, based on the equation of motion and Green’s function method. COM uses propagators of composite operators as building blocks at the basis of approximate calculations and algeb...
