Universal center-of-mass scaling shapes segment fluctuations and chromatin dynamics
We show that cancellation of internal forces together with spatially uncorrelated noise generically enforces a universal $1/s$ scaling of the center-of-mass (COM) diffusivity for polymer segments of contour length $s$, independent of model details. Within…
