Globule-coil transition in the dynamic HP model

Kamilla Faizullina, Evgeni Burovski.

We consider a dynamic version of the HP model of a linear polymer: a self-avoiding
walk on the square lattice, with monomers being either hydrophobic (H) or polar (P). We
simulate the model in two dimensions in the grand canonical assemble via the Berretti-Sokal
algorithm across the globule-coil transition and map out the phase diagram. Our results are
consistent with the universality class of the transition being the same as the universality class
of the theta-transition of an interacting self-avoiding walk.
