Dynamical Spin-Blockade in a quantum dot with paramagnetic leads | A. Cottet

23 Dec 2003 | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | Abstract: | We 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. | Source: | arXiv, cond-mat/0401456 | Services: | Forum | Review | PDF | Favorites |
