The equilibrium winding angle of a polymer around a bar KU Leuven
The probability distribution of the winding angle theta of a planar self-avoiding walk has been known exactly for a long time: it has a Gaussian shape with a variance growing as similar to ln L. For the three-dimensional case of a walk winding around a bar, the same scaling is suggested, based on a first-order epsilon-expansion. We tested this three-dimensional case by means of Monte Carlo simulations up to length L approximate to 25 000 and ...
