Tissue shape from cell-scale active tensions
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Connecting cell behavior to tissue shape and mechanics is a key challenge in the physics of morphogenesis. Cytoskeletal turnover precludes a fixed reference state, and tensions are…

Emergent Elasticity and Quasiconformal Flow in Active Solids
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
A constitutive relation between stress and strain relative to a reference state is the basic assumption of elasticity theory. However, in living matter, force generation is governe…
