STM conductance of Kondo impurities on open and structured surfaces
P. S. Cornaglia, C. A. Balseiro
We study the scanning tunneling microscopy response for magnetic atoms on open and structured surfaces using Wilson's renormalization group. We observe Fano resonances associated w…
Transport through quantum dots in mesoscopic circuits
P. S. Cornaglia, C. A. Balseiro
We study the transport through a quantum dot, in the Kondo Coulomb blockade valley, embedded in a mesoscopic device with finite wires. The quantization of states in the circuit tha…
Spectral densities of Kondo impurities in nanoscopic systems
P. S. Cornaglia, C. A. Balseiro
We present results for the spectral properties of Kondo impurities in nanoscopic systems. Using Wilson's renormalization group we analyze the frequency and temperature dependence o…
Kondo impurities in nanoscopic systems: new confinement-induced regimes
P. S. Cornaglia, C. A. Balseiro
We present results for Kondo impurities in nanoscopic systems. Using exact diagonalization in small clusters and Wilson's renormalization group we analyze an isolated system and a…
