Feedback-controlled mechanics of tissue vertex model: emergent soft elasticity and active yielding
Pengyu Yu, Fridtjof Brauns, M. Cristina Marchetti
Biological tissues exhibit diverse mechanical and rheological behaviors during morphogenesis. While much is known about tissue phase transitions controlled by structural order and…
Proliferating Nematic That Collectively Senses an Anisotropic Substrate
Toshi Parmar, Fridtjof Brauns, Yimin Luo +1
Motivated by recent experiments on growing fibroblasts, we examine the development of nematic order in a colony of elongated cells proliferating on a nematic elastomer substrate. A…
Topology and Kinetic Pathways of Colloidosome Assembly and Disassembly
Raymond Adkins, Joanna Robaszewski, Seungwoo Shin +7
Liquid shells, such as lipid vesicles and soap bubbles, are ubiquitous throughout biology, engineered matter, and everyday life. Their creation and disintegration are defined by a…
Active Solids: Topological Defect Self-Propulsion Without Flow
Fridtjof Brauns, Myles O'Leary, Arthur Hernandez +2
The self-propulsion of +1/2 topological defects is a hallmark of active nematic fluids, where the defects are advected by the flow field they themselves generate. In this paper we…
