Dynamical Spin-Blockade in a quantum dot with paramagnetic leads
A. Cottet ; W. Belzig ;
Date 23 Dec 2003
Subject Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall
AbstractWe investigate current fluctuations in a three-terminal quantum dot in the sequential tunneling regime. Dynamical spin blockade can be induced when the spin-degeneracy of the dot states is lifted by a magnetic field. This results in super-Poissonian shot noise and positive zero-frequency cross-correlations. Our proposed setup can be realized with semiconductor quantum dots.
