Polymer pinning in a random medium as influence percolation
Vincent Beffara, Vladas Sidoravicius, Herbert Spohn +1
In this article we discuss a set of geometric ideas which shed some light on the question of directed polymer pinning in the presence of bulk disorder. Differing from standard meth…

Smoothing effect of quenched disorder on polymer depinning transitions
G. Giacomin, F. L. Toninelli
We consider general disordered models of pinning of directed polymers on a defect line. This class contains in particular the --dimensional interface wetting model, the diso…

Estimates on path delocalization for copolymers at selective interfaces
Giambattista Giacomin, Fabio Lucio Toninelli
We consider a directed random walk model of a random heterogeneous polymer in the proximity of an interface separating two selective solvents. This model exhibits a localization/de…
