【 摘 要 】

The effect of strong singularity in the calculation of range function for the RKKY interaction in 1D electron gas is discussed. The method of handling this singularity is presented. A possible way of avoiding the singularity in the Ruderman-Kittel perturbation theory in 1D is described. (C) 2017 Elsevier B. V. All rights reserved.
