The authors wish to make the following corrections to this paper: [1]. In Section 4.4 of the original publication, the torsional autocorrelation functions of the confined melts are shown on the frequency domain. The employed relation is provided in page 16 of the original publication. A factor of $2\pi$ has been omitted from that relation, and it should be replaced with: ${\epsilon }_{\mathrm{T}}^{{}^{″}}\left(f\right)=2\pi f{\int }_0^{\infty }\mathrm{TACF}\left(t\right)cos\left(2\pi ft\right)dt$, where f is frequency. In fact, in the original publication, the spectra are plotted as functions of angular frequency.

Because of the above mentioned $2\pi$ factor, the spectra shown in Figure 11, in Figure 12a, and in a part of the graphical abstract (Figure 11d is also presented there) should be horizontally shifted on the logarithmic scale. The updated figures are provided below. The rest of the paper’s figures and all discussions and conclusions remain unaltered. The original article has been updated.
