Shape transitions of high-genus fluid vesicles

الأصل · EN

The morphologies of genus-2 to -8 fluid vesicles are studied by using dynamically triangulated membrane simulations with area-difference elasticity. It is revealed that the alignments of the membrane pores alter the vesicle shapes and the types of shape transitions for the genus g ≥ 3. At a high reduced volume, a stomatocyte with a circular alignment of g+1 pores continuously transforms into a discocyte with a line of g pores with increasing intrinsic area difference. In contrast, at a low volume, a stomatocyte transforms into a (g+1)-hedral shape and subsequently exhibits a discrete phase transition to a discocyte.
