RKKY to Kondo crossover in helical edge of a topological insulator

RKKY to Kondo crossover in helical edge of a topological insulator

Two spatially separated magnetic impurities coupled to itinerant electrons give rise to a dynamically generated exchange (RKKY) inter-impurity interaction that competes with the individual Kondo screening of the impurities. It has been recently shown by Yevtushenko and Yudson [Phys. Rev. Lett. 120,...
