Julien POISAT (Université Paris Dauphine): Phase transitions in charged polymer models

Julien POISAT: I will review some old and recent results on the topic of charged polymer models. Those are random walk models with disordered interaction at self-intersections, introduced by Kantor and Kardar in the 90’s. Precise results have been obtained so far for the one-dimensional model in the annealed setting, showing a phase transition from a collapsed phase (attractive interactions prevai
