Morphology change in nematic membranes induced by defects

Abstract: ABSTRACT. The cell membrane is one of the most important structures of living organisms. This is due to the many functions attributed to it such as permeable selectivity, protection, anchoring to the cytoskeleton and so many others. Any change in the shape of the cell membrane may affect directly the properties and abilities. In this article, we study how defects in the liquid crystalline organization of a membrane can change its shape. For performing this, we consider a membrane with orientational order, i.e.… Show more

“…In the previous analytical description of membrane buckling induced by disclinations, cone-like configurations are assumed. This is probably a good approximation, however, recent numerical analysis of the corresponding free energy suggests that the equilibrium configurations rather resemble pseudo-spheres [39]. In their study free energy minimisation was only considered for + 1 p disclinations, which appear naturally for a spherical p-atic membrane.…”
