  • Ergodicity in strongly correlated systems 
    Avella, A.; Mancini, F.; Plekhanov, E. (Condensed Matter Physics, 2006)
    We present a concise and systematic review of the ergodicity issue in strongly correlated systems. After giving a brief historical overview, we analyze the issue within the Green’s function formalism by means of the ...
  • Green’s function formalism for highly correlated systems 
    Mancini, F.; Avella, A. (Condensed Matter Physics, 2006)
    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 ...
  • Symmetries in the physics of strongly correlated electronic systems 
    Mancini, F.; Avella, A. (Condensed Matter Physics, 1998)
    Strongly correlated electron systems require the development of new theoretical schemes in order to describe their unusual and unexpected properties. The usual perturbation schemes are inadequate and new concepts ...
  • The composite operator method route to the 2D Hubbard model and the cuprates 
    A. Di Ciolo; Avella, A. (Condensed Matter Physics, 2018)
    In this review paper, we illustrate a possible route to obtain a reliable solution of the 2D Hubbard model and an explanation for some of the unconventional behaviours of underdoped high-Tc cuprate superconductors within ...
