Phase diagrams of confined square lattice linked polygons

The phase diagrams of two models of two confined and dense two-dimensional ring polymers are examined numerically. The ring polymers are modeled by square lattice polygons in a square cavity and are placed to be either unlinked or linked in the plane. The phase diagrams of the two models are found to be a function of the placement of the ring polymers and include multicritical points where first-order and continuous phase boundaries meet. We estimate numerically the critical exponents associated with the phase boundaries and the multicritical points.

Automated summary

The study examines the phase diagrams of two confined and dense two-dimensional ring polymer models numerically, finding that the phase diagrams are a function of the placement of the ring polymers and include multicritical points. Numerical estimates of critical exponents associated with phase boundaries and multicritical points were obtained.
