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. ...

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 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. ...

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 ...

We study numerically the frequency modulated kicked nonlinear rotator with effective dimension d = 1, 2, 3, 4. We follow the time evolution of the model up to 109 kicks and determine the exponent α of subdiffusive spreading ...

In this work we present a study on the phenomenon of dynamic localization for multidimensional discrete Anderson model, through the method of fractional moments of the Green’s function in infinite and finite volumes. We ...
