Local moment formation in quantum point contacts
Kenji Hirose, Yigal Meir, Ned S. Wingreen
Spin-density-functional theory of quantum point contacts (QPCs) reveals the formation of a local moment with a net of one electron spin in the vicinity of the point contact - suppo…
Kondo model for the "0.7 anomaly" in transport through a quantum point contact
Yigal Meir, Kenji Hirose, Ned S. Wingreen
Experiments on quantum point contacts have highlighted an anomalous conductance plateau at , with features suggestive of the Kondo effect. Here we present an Anderson…
Ground-state energy and spin in disordered quantum dots
Kenji Hirose, Ned S. Wingreen
We investigate the ground-state energy and spin of disordered quantum dots using spin-density-functional theory. Fluctuations of addition energies (Coulomb-blockade peak spacings)…
The Low-Temperature Fate of the 0.7 Structure in a Point Contact: A Kondo-like Correlated State in an Open System
S. M. Cronenwett, H. J. Lynch, D. Goldhaber-Gordon +5
Besides the usual conductance plateaus at multiples of 2e2/h, quantum point contacts typically show an extra plateau at ~ 0.7(2e2/h), believed to arise from electron-electron inter…
