报告摘要:
The observation of the morphological transition of the human red blood cell from discoid shape to the spherical one ususally signals certain fatal human diseases. We study the relationshop between RBCs' equilibrium shapes and their mechanical properties, and proposed a geometric approach to describe the morphological transiton by a phase diagram. Graphene is the thinnest material in the world with only one-atomic-layer thickness. We apply the geometric methods developed originally in the study of biological membranes to the new research on structural deformations, electromechanical coupling, and Raman spectroscopy of the graphene. Our work draws a fruitful parallel between an extensively studied biological system and a new type of condensed matter material.
