Current induced entanglement of nuclear spins in quantum dots
Abstract
We propose an entanglement mechanism of nuclear spins in quantum dots driven by the electric current. The current accompanied by the spin flip in quantum dots gradually increases components of larger total spin of nuclei. This entangled state drastically enhances the spin relaxation rate of electrons, which can be detected by measuring a leakage current in the spin-blockade region. This mechanism is not relevant in optical experiments which examine the spin relaxation of single excitations.
