Kondo Effect in Systems with Spin Disorder
Igor E. Smolyarenko, Ned S. Wingreen
We consider the role of static disorder in the spin sector of the one- and two-channel Kondo models. The distribution functions of the disorder-induced effective energy splitting b…
Observation of a Nanoscale Metallic Dot Self-Consistently Coupled to a Two-Level System
D. E. Grupp, T. Zhang, G. J. Dolan +1
We have observed anomalous transport properties for a 50 nm Bi dot in the Coulomb-blockade regime. Over a range of gate voltages, Coulomb blockade peaks are suppressed at low bias,…
How long does it take for the Kondo effect to develop?
Peter Nordlander, Michael Pustilnik, Yigal Meir +2
The time-development of the Kondo effect is theoretically investigated by studying a quantum dot suddenly shifted into the Kondo regime by a change of voltage on a nearby gate. Usi…
