# Mean-field tricritical polymers

@inproceedings{Bauerschmidt2019MeanfieldTP, title={Mean-field tricritical polymers}, author={Roland Bauerschmidt and Gordon Slade}, year={2019} }

We provide an introductory account of a tricritical phase diagram, in the setting of a mean-field random walk model of a polymer density transition, and clarify the nature of the density transition in this context. We consider a continuous-time random walk model on the complete graph, in the limit as the number of vertices $N$ in the graph grows to infinity. The walk has a repulsive self-interaction, as well as a competing attractive self-interaction whose strength is controlled by a parameter… CONTINUE READING
