Spectral properties and persistent currents of small metallic clusters

Mostrar todas las versiones(2)

The effects of surface roughness and confinement on the spectral properties of bidimensional metallic loops threaded by a magnetic flux are analyzed. At half filling, the existence of localized border states is shown. At zero flux, these states are degenerated, with energy very close to zero. They b...
