Interaction between Kondo impurities in a quantum corral

Mostrar todas las versiones(2)

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 pre...

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.
