triangulax: Differentiable Simulations with Triangular Meshes across Soft Matter Physics
Samuel Silliman, Qiwei Yu, Nikolas Claussen
Many physical and biological systems -foams, membranes, elastic shells, or tissue sheets- can be mathematically described as 2D surfaces. These surfaces can host complex dynamics,…
Tissue shape from cell-scale active tensions
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Connecting cell and tissue mechanics is a fundamental challenge in the physics of morphogenesis. Conventional elasticity theory is generally inapplicable: cytoskeletal turnover pre…
Emergent Elasticity and Quasiconformal Flow in Active Solids
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Elasticity theory rests on a constitutive relation between stress and strain relative to a reference state. Living matter, however, generates forces by motor molecule activity inde…
A Mean-Field Model for Active Plastic Flow of Epithelial Tissue
Nikolas H. Claussen, Fridtjof Brauns
Animal morphogenesis often involves significant shape changes of epithelial tissue sheets. Great progress has been made in understanding the underlying cellular driving forces and…
