These authors have considered the problem of electron spin dephasing due to the hyperfine interaction for an ensemble of dots. They observed several time scales for this problem with different decay laws. For the initial electron spin decay which is due to the different nuclear magnetic fields realized in different dots they obtained essentially the same formula that we derived (Ref. 9), Eq. (39), with the same time scale (Formula presented).
