Anomalous Kondo Effect in a Quantum Dot at Nonzero Bias
Anomalous Kondo Effect in a Quantum Dot at Nonzero Bias
We present measurements on the Kondo effect in a small quantum dot connected strongly to one lead and weakly to the other. The conductance of the dot reveals an offset of the Kondo resonance at zero magnetic field. While the resonance persists in the negative bias regime, it is suppressed …
