Polymerized membranes in poor solvent
We discuss the mechanism of the phase transitions of polymerized membranes with attractive interactions or in poor solvent. Depending on the local flexibility of the membrane, the membranes with attractive interactions are known to show a discontinuous or a continuous flat-compact phase transitions. We study a model for D-dimensional polymerized membrane with attractive long-range interactions (r−y) and a square-lattice model with bending rigidity (u) and repulsive or attractive interactions (±ω). Based on the results, we give a theoretical interpretation to the flat-compact phase transition of polymerized membranes.
