Abstract:
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 (formula presented) observed in the quantum mirage experiment is reproduced. In presence of another impurity (formula presented) is very sensitive to the hybridization between impurity and bulk. The impurities are correlated ferromagnetically between them. A hopping (formula presented) between impurities destroys the Kondo resonance. © 2002 The American Physical Society.
