Nonlinear Relaxation in Population Dynamics
M. A. Cirone, F. de Pasquale, B. Spagnolo
We analyze the nonlinear relaxation of a complex ecosystem composed of many interacting species. The ecological system is described by generalized Lotka-Volterra equations with a m…

The Charge Ordered State from Weak to Strong Coupling
S. Ciuchi, F. de Pasquale
We apply the Dynamical Mean Field Theory to the problem of charge ordering. In the normal state as well as in the Charge Ordered (CO) state the existence of polarons, i.e. electron…

Dynamical mean-field theory of the small polaron
S. Ciuchi, F. de Pasquale, S. Fratini +1
A dynamical mean-field theory of the small polaron problem is presented, which becomes exact in the limit of infinite dimensions. The ground state properties and the one-electron s…
