Quantum correlations in nanostructured two-impurity Kondo systems
Marco Nizama, Diego Frustaglia, Karen Hallberg
We study the ground-state entanglement properties of nanostructured Kondo systems consisting of a pair of impurity spins coupled to a background of confined electrons. The competit…
Two-state behaviour of Kondo trimers
M. E. Torio, K. Hallberg, C. R. Proetto
The electronic properties and spectroscopic features of a magnetic trimer with a Kondo-like coupling to a non-magnetic metallic substrate are analyzed at zero temperature. The subs…
Spin filters with Fano dots
M. E. Torio, K. Hallberg, S. Flach +2
We compute the zero bias conductance of electrons through a single ballistic channel weakly coupled to a side quantum dot with Coulomb interaction. In contrast to the standard setu…
