Abstract

Recent advances in Monte Carlo algorithms for systems of interacting electrons have made possible the detailed study of the spatial dependence of spin and charge correlations in the Anderson single impurity model. The hamiltonian for this model [1]
$$H=\sum\limits_{ks}{{{\varepsilon }_{k}}+{{n}_{ks}}+\sum\limits_{k}{({{v}_{kd}}c_{ks}^{+}{{c}_{ds}}+v_{dk}^{*}c_{ds}^{+}{{c}_{ks}})}}+{{\varepsilon }_{d}}\sum\limits_{s}{{{n}_{ds}}}+U{{n}_{d\uparrow }}{{n}_{d\downarrow }}$$

has a non-degenerate impurity state with energy εd hybridized with strength Vkd to energy states εk of some conduction band. In addition it has a Coulomb interaction U between electrons with oppositely paired spins that try to occupy the impurity state.
