We present a microscopic examination for the itinerant-localized duality model which has been proposed to understand anomalous properties of strongly correlated systems like the heavy fermions by Kuramoto and Miyake, and also useful to describe the anomalous properties of the high- T c cupurates. The action of the duality model consists of two components of dynamical degrees of freedom. One of them is coherent itinerant degree of fermion and the other is incoherent localized one describing… Expand

Induced-moment weak antiferromagnetism and orbital order on the itinerant-localized duality model with nested fermi surface : A possible origin of exotic magnetism in URu2Si2
The weak antiferromagnetism of URu 2 Si 2 is discussed on the basis of a duality model which takes into account salient features of both itinerant fermions and “localized” component of spin degreesExpand
Realization of Odd-Frequency p-Wave Spin-Singlet Superconductivity Coexisting with Antiferromagnetic Order near Quantum Critical Point
A possibility of the realization of the p -wave spin–singlet superconductivity ( p SS), whose gap function is odd both in momentum and in frequency, is investigated by solving the gap equation withExpand

We present an exact mapping of the Hubbard model in infinite dimensions onto a single-impurity Anderson (or Wolff) model supplemented by a self-consistency condition. This provides a mean-fieldExpand
Itinerant-localized duality picture of spin fluctuations in high-Tc cuprates. I: Nested spin-fluctuation theory

A review is given on the duality theory which describes strongly correlated electron systems with account of dichotomy between itinerant and localised characters. As a specific application, the weakExpand
A “fermi-liquid” description of the Kondo problem at low temperatures
We take as granted Anderson's statement that in the low-temperature limit the usual Kondos-d model evolves toward a fixed point in which the effective exchange coupling of the impurity with theExpand

Abstract We propose a microscopic justification for the recently proposed “marginal Fermi-liquid” (MFL) phenomenology of the high T c materials. In some models, and for sufficiently strongExpand
