Phys. Rev. Lett. 59, 1989–1992 (1987)Thermodynamic behavior of two-dimensional vesiclesReceived 26 August 1987; published in the issue dated 2 November 1987 A Monte Carlo simulation of two-dimensional vesicles, modeled as closed, planar, self-avoiding tethered chains is presented. The effects of an internal pressure increment, Δp, and a bending rigidity, κ, on the sizes and shapes is studied. For κ=0 scaling behavior is found, which, in the asymptotic deflated regime, Δp<0, matches the behavior of branched polymers. For κ>0 various nontrivial equilibrium shapes or cytotypes appear and dynamical behavior reminiscent of nonlinear flickering in real vesicles is found. © 1987 The American Physical Society URL:
