Abstract
The effect of conduction-electron interactions for an Anderson impurity is investigated in one dimension using a scaling approach. The flow diagrams are obtained by solving the renormalization-group equations numerically. It is found that the Anderson impurity case is different from its counterpart, the Kondo impurity case, even in the local moment region. The Kondo temperature for an Anderson impurity shows nonmonotonic behavior, increasing for weak interactions but decreasing for strong interactions. The implication of the study to other related impurity models is also discussed.
