    Abstract

    We have studied the correlations between an Anderson magnetic impurity and its surrounding conduction electrons using a Monte Carlo simulation technique. Results for spin and charge correlations for a symmetric Anderson impurity in a free-electron continuum are presented. Our results show the spatial structure of the spin-compensation cloud that forms around the magnetic impurity as the temperature is lowered, and the suppression of the charge-density correlations caused by the Kondo effect.
