Abstract

Using the nonperturbative Lanczos recursion scheme an analytic approximation to the ground-state energy of the single-impurity Anderson model is obtained. Calculations are carried out to a 5\ifmmode\times\else\texttimes\fi{}5 matrix truncation. Comparisons are made with the exact Bethe-ansatz result.

Strongly correlated electron ground-state energy approximations for Anderson-like models

Jay D. Mancini, Charles D. Potter, Samuel P. Bowen

We report preliminary results of convergence properties for nonperturbative resolvent approximations to Anderson-like models of magnetic ions in metals. Our study is initially focused on the spin- 1/2 Anderson model for magnetic impurities, but the methods studied can include multiplet and crystal-field effects which are needed for more accurate descriptions of real systems. We will compare the nonperturbative Lanczos method (tridiagonalization) and similar truncation schemes to exact ground-state energies for the impurity model and assess the efficacy of these nonperturbative approaches to understanding the Anderson lattice, heavy fermions, and other strongly interacting electronic systems.

Finite-basis many-electron approximation to the Anderson model

Jay D. Mancini, Samuel P. Bowen, Yu Zhou

A relatively simple many-electron basis is used to construct a matrix for the Anderson impurity Hamiltonian. The basis states are each valid in the thermodynamic limit. The approximate ground-state energy compares well with Bethe-ansatz results for large Coulomb energies. The ground-state wave-function properties are not as well approximated. This method may be well suited to studies of more realistic Hamiltonians and their ground-state energy and its derivatives.

An important equation for the Anderson model

Baohua Teng

This paper proves an important equation for the Anderson model. Then, using this equation we deal exactly with the Anderson model and obtain the exact analytical expression for the ground-state energy. This result coincides with the result of the Bethe ansatz.

Approximations to the ground-state energy of the single-impurity Kondo model using variational and connected-moments expansions

Jay D. Mancini, Janice D. Prie, William J. Massano

We have studied the ground-state energy of the single-impurity Kondo model. Results using a strict 4\ifmmode\times\else\texttimes\fi{}4 Lanczos truncation are shown to be equivalent to a relaxed 26\ifmmode\times\else\texttimes\fi{}26 Lanczos basis. An application of the connected-moments expansion to obtain the ground-state energy of this model many-body Hamiltonian is shown to be limited to certain regions of parameter space.

On the ground state energy of the symmetric Anderson model

Kazuhiro Ueda, W. Apel

In this article the authors examine the analytic structure of the Bethe ansatz solution for the ground state energy of the symmetric Anderson model as a function of the interaction U. They find that the energy is analytic for all real U and examine also the strong coupling limit U to infinity .

Self-consistent hybridization expansions for static properties of the Anderson impurity model

Building an effective Hamiltonian utilizing a projector-operatorprocedure, we derive an approximation based on a selfconsistenthybridization expansion to study the ground stateproperties of the Anderson Impurity model.We applied the approximationto the general case of finite Coulomb repulsionU, extending previous work with the same formalism in theinfinite-U case. The ground state energy and their related zerotemperature properties are accurately obtained in the case inwhich U is large enough, but still finite, as compared with the rest of energy scales involved in the model. The results for thevalence of the impurity are compared with exact results thatwe obtain from equations derived using the Bethe ansatz andwith a perturbative approach. The magnetization and magneticsusceptibility is also compared with Bethe ansatz results. Inorder to do this comparison, we also show how to regularizethe Bethe ansatz integral equations necessary to calculate theimpurity valence, for arbitrary values of the parameters.
