Exchange Control of Nuclear Spin Diffusion in a Double Quantum Dot

Exchange Control of Nuclear Spin Diffusion in a Double Quantum Dot

The influence of gate-controlled two-electron exchange on the relaxation of nuclear polarization in small ensembles (N∼10[superscript 6]) of nuclear spins is examined in a GaAs double quantum dot system. Waiting in the (2,0) charge configuration, which has large exchange splitting, reduces the nucle...
