(a) Graphical representation of three quantities discussed in the text: the height of the barrier, ${ϵ}_b$, the depth of the minimum, ${ϵ}_d$, and the interaction distance, $D_{\mathrm{int}}$; (b) Dependence of the height of the barrier and the depth of the free energy minimum on the polymer bending rigidity, ${\kappa }_b$.
