Two Impurity Anderson problem: Perturbative Kondo-Doublet interaction
J. Simonin
We reobtain the Kondo-Doublet interaction by means of the Brillouin-Wigner Perturbation theory. By applying the same method to the single impurity case we show that the Kondo-Doubl…
Looking for the Kondo cloud
Jorge Simonin
We study the spatial distribution of the Kondo screening cloud. We find that in 3 D the spatial range of the cloud is limited to distances of the order of the Fermi wavelength due…
Two Anderson Impurities in the Kondo Limit, Doublet States
J. Simonin
We analyze two pairs of doublet states for the two Anderson impurity problem. We found that for short interimpurity distances they have a lower energy than the ferro triplet and th…
Two Anderson Impurities in the Kondo Limit. Systematic Study
J. Simonin
We analyze the two Anderson impurity problem, in the strong Coulomb repulsion limit, by means of variational wave functions whose equations we solve analytically. We found two pair…
