Fig. 2: Depth-resolved dynamical properties.
a Mean squared displacement (MSD) and (b) intermediate scattering function Fs(q, t) for different z values (in units of σs): −25, −15, −5, 5, 15, 25, 35, 45, 55, 65, 75, 85, 95 (in the direction of the arrow) where q = 1.45 μm−1 corresponds to the first peak in the structure factor at φsat. Each bin is averaged over a width of z ± 5σs. The data is taken at ΔT = 4.5 K. The black solid line corresponds to the slope equal to 1.
