Coarse-Grained Quantities and Local Environment Effects in Disordered Systems
Coarse-Grained Quantities and Local Environment Effects in Disordered Systems
Goda, Masaki
It is proved that the effective “distance” m(ε+iΓ) , proposed first by Matsuda for a linear chain model with nearest-neighbour interaction, exists in any dimensional disordered systems described by a bounded Hamiltonian with short-range interaction. Thus the local situation or short-range order plays an essential role in determining various physical quantities in the sense that the Green function Gl.l'(ε+iΓ) is almost determined by the local situation of the system at and around the sites l and l'.
