Hyperfine-Induced Decay in Triple Quantum Dots
arXiv:1204.4844 · doi:10.1103/PhysRevB.86.125408
Abstract
We analyze the effects of hyperfine interactions on coherent control experiments in triple quantum dots. By exploiting Hamiltonian symmetries and the SU(3) structure of the triple-dot system under pseudo-exchange and longitudinal hyperfine couplings, we provide analytic formulae for the hyperfine decay of triple-dot Rabi and dephasing experiments.
