Dynamical Spin-Blockade in a quantum dot with paramagnetic leads
arXiv:cond-mat/0401456 · doi:10.1209/epl/i2004-10009-9
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.
