Writhe distribution of stretched polymers.
Motivated by experiments in which single deoxyribose nucleic acid molecules are stretched and twisted we consider a perturbative approach around very high forces, where we determine the writhe distribution in a simple, analytically tractable model. Our results are in agreement with recent simulations and experiments.
