A zipper has N links, and each has a "closed" state with energy 0 and an "open" state with energy
A zipper with N links. Each link has 2 states: closed (energy = 0) and open (energy = E). We require that the zipper can only unzip from the left end, and that the link number s can only open if all links to the left (1,2,..., s-1) are already open. (a) What is the partition function for the zipper? (b) What is the average number of open links in the limit (i) >> τ and (ii) << τ
