Quantum criticality in Kondo quantum dot coupled to helical edge states of interacting 2D topological insulators

POSTER

Abstract

We investigate theoretically the quantum phase transition (QPT) between the one-channel Kondo (1CK) and two-channel Kondo (2CK) fixed points in a quantum dot coupled to helical edge states of interacting 2D topological insulators (2DTI) with Luttinger parameter $0
