Effect of strong correlation on the study of renormalization group flow diagram for Kondo effect in a interacting quantum wire

TL;DR

This paper investigates how strong electronic correlations influence the renormalization group flow and fixed points in the Kondo effect within an interacting quantum wire, revealing conditions for single or two-channel Kondo behavior.

Contribution

It introduces an analysis of the impact of strong correlations on the Kondo effect's RG flow and fixed point stability in quantum wires, highlighting the role of initial coupling constants.

Findings

Behavior switches between single and two-channel Kondo effects based on initial conditions.

Strong correlations significantly alter the RG flow and fixed point stability.

The study provides insights into impurity effects in correlated quantum systems.

Abstract

We present the study of Kondo effect in an interacting quantum wire. We mainly emphasis the effect of strong electronic correlations in the study of renormalization group flow diagram and the stability analysis of fixed points for both magnetic and nonmagnetic impurities. We observe that the behavior of the system is either in the single channel or in the two channel Kondo effect depending on the initial values of coupling constants and strong correlations.
