The two-impurity Anderson model: An effective medium approach
(2002-03-01)
The two-impurity Anderson model is solved within a effective medium approach. All impurity parameters are modelled via Slater atomic orbitals. Impurity spectral densities and spin correlation functions are readily computed. ...

Universal conductance for the Anderson model
(2010-09-30)
We discuss the thermal dependence of the zero-bias electrical conductance for a quantum dot embedded in a quantum wire, or side-coupled to it. In the Kondo regime, the temperature-dependent conductances map linearly onto ...

The Holstein-Anderson impurity model
(2001-12-01)
A Holstein-Anderson impurity model is presented. Both the electronic states and the vibrational mode associated to the impurity are treated within a novel 'entangled' effective medium approach (a non-perturbative, ...

Densidade de Estados para o Modelo de Anderson Discreto
(Universidade Estadual Paulista (Unesp), 2019-02-22)
O presente trabalho tem como objetivo principal estudar a densidade de estados para o modelo de Anderson discreto multidimensional. Tal modelo constitui uma família de operadores de Schrödinger aleatórios e ergódicos. ...
Spin-resolved local density of states for an Anderson adatom in a ferromagnetic island
(2013-06-01)
In this work, we investigate theoretically the spin-resolved local density of states (SR-LDOS) of a ferromagnetic (FM) island hybridized with an adatom, which is described by the Single Impurity Anderson Model (SIAM). Our ...
