Two impurity Kondo problem under Aharonov--Bohm and Aharonov--Casher Effects
arXiv:cond-mat/0608587 · doi:10.1103/PhysRevB.76.073304
Abstract
We investigate electron transport under the two impurity Kondo problem with the Aharonov--Bohm and Aharonov--Casher effects. These interference effects induce the Ising-coupled Ruderman--Kittel--Kasuya--Yosida (RKKY) interaction. We discuss the inter- and intra-site spin conductance as well as charge conductance in the Kondo and the mixed-valence regimes using the slave boson mean field approximation.
