ecIn recent years there has been a renewed interest in study of strongly correlated electron materials. These terials exhibit interesting phenomena like the correlat induced metal insulator transition [1–3]. A very prom ing method capable of providing a theoretical descripti perhaps, is the limit of large spatial dimensions [4], wh defines a dynamical mean field theory for the proble This limit can be mapped onto an impurity model toget with a self-consistency condition which is characteris for… CONTINUE READING
