【 摘 要 】
The RKKY law and the Kondo screening cloud around a magnetic impurity are investigated for correlated electrons in one dimension (Luttinger liquid). We find slow algebraic distance dependences, with a crossover between both types of behavior. Monte Carlo simulations have been developed to study this crossover. In the strong-coupling regime, the Knight shift is shown to increase with distance due to correlations.
