Kondo effect in quantum dots coupled to ferromagnetic leads
We study the Kondo effect in a quantum dot coupled to ferromagnetic leads and analyze its
properties as a function of the spin polarization of the leads. Based on a scaling approach …

A quantum dot in the limit of strong coupling to reservoirs
J Schmid, J Weis, K Eberl, K Klitzing - Physica B: Condensed Matter, 1998 - Elsevier
We study quantum dots which are defined in a two-dimensional electron system (2DES) via
split gates and concentrate on the case where the dots are strongly coupled to reservoirs. At …
