Interaction between Kondo impurities in a quantum corral
We calculate the spectral densities for two impurities inside an elliptical quantum corral, using exact diagonalization in the relevant Hilbert subspace and embedding into the rest of the system. For one impurity, the space and energy dependence of the change in differential conductance ΔdI/dV obser...

| Sumario: | We calculate the spectral densities for two impurities inside an elliptical quantum corral, using exact diagonalization in the relevant Hilbert subspace and embedding into the rest of the system. For one impurity, the space and energy dependence of the change in differential conductance ΔdI/dV observed in the quantum mirage experiment is reproduced. In presence of another impurity ΔdI/dV is very sensitive to the hybridization between impurity and bulk. The impurities are correlated ferromagnetically between them. A hopping ≳0.15 eV between impurities destroys the Kondo resonance. |
