Autocorrelation functions of displacement of single nucleosomes and the density of vibrational modes. (A) The autocorrelation function of single-nucleosome displacement, ${\eta }^a\left(t\right)$, is plotted as a function of $t$. Bars show the standard errors among 10 cells. (B) The density of vibrational modes, $D^a\left(\omega \right)$, is plotted as a function of frequency $\omega$ for 10 cells. In A and B, curves are plotted for fast ($a=f$; black) and slow ($a=s$; red) nucleosomes.
