    • During the pumping for Ti =60s, nuclear polarization diffuses to √ D Ti ∼24nm (see discussion in Sec. ). However, the profile in the close vicinity of X ≈ Xi is rather dominated by the distribution of the directly pumped polarization.

    • This interpretation is supported by additional experiments not described here: at elevated temperatures up to 500 mK, the backgroundlike component of polarization (in a deeper region of X> Xi +100nm) is found to increase its amplitude, whereas the component of polarization around X ≈ Xi diminishes. These findings indicate that phonon-assisted processes are relevant to the generation of the backgroundlike polarization.

    • It would be straightforward to adopt the smallest current (0.1 nA) for simpler interpretation. We chose, however, Ii =±5nA because (i) generated polarization is large enough to be probed in a single-shot measurement and (ii) a broader distribution of polarization enables observation of the decay process at different positions (X).
