Beyond the Nca: New Results for the Spectral Properties of the Anderson Model
In the framework of direct perturbation theory a fully self-consistent approximation beyond the well known NCA will be presented for the Anderson Model. The resummation of a class of skeleton diagrams up to innnite order in V includes all contribution up to the order O(1=N 2) (N = dege-neracy of the magnetic state). Qualitative improvements in maintaining local Fermi-Liquid relations and one-pa...
متن کاملSpectral Properties of Anderson-percolation Hamiltonians
In this report we will for simplicity restrict ourselves to the following situation. We consider the graph with vertex set Z, where two of the vertices are joined by an edge if their l distance is equal to one. The group Γ := Z is acting on the graph by translations. Denote by {ΛL}L∈2N the exhaustion of Z by cubes ΛL := Z ∩ [−L/2, L/2]. We construct a probability space (Ω,A,P) associated to per...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولSpectral Properties of the Anderson Impurity Model: Comparison of Numerical Renormalization Group and Non–Crossing Approximation
A comparative study of the numerical renormalization group and non– crossing approximation results for the spectral functions of the U = ∞ Anderson impurity model is carried out. The non–crossing approximation is the simplest conserving approximation and has led to useful insights into strongly correlated models of magnetic impurities. At low energies and temperatures the method is known to be ...
