WebNov 7, 2024 · According to the Rouse model, 56 the relaxation time of a freely-draining chain scales with chain length as τ rouse ∝ L 1+2 v, where L is the contour length and ν = 0.588 is the excluded volume Flory exponent. 55 For a knotted molecule, the free chain contour that is allowed to relax is L free = L chain − L knot. Hence, we have WebSpecifically, by extracting the Flory exponent of the active polymer under different conditions, we are able to pin down the location of the coil–globule transition for different strengths of the active forces. Remarkably, we find that a simple rescaling of the temperature is capable of qualitatively capturing the dependence of the Θ -point ...
