Universal scaling in the rheology of dense cellular systems
Helen S. Ansell, Daniel M. Sussman
Biological tissues must dynamically transition between rigid and fluid-like states during processes like morphogenesis and collective migration, often while simultaneously resistin…
Models of 3D confluent tissue as under-constrained glasses
Chengling Li, Matthias Merkel, Daniel M. Sussman
The dynamics of glassy materials slows down upon cooling, typically showing either Arrhenius or super-Arrhenius behavior. However, it was recently shown that 2D cell-based models f…
Geometric control of motility-induced phase separation
Toler H. Webb, Helen S. Ansell, Daniel M. Sussman
Curvature fundamentally alters the collective properties of soft, active, and biological materials. Here we study motility-induced phase separation (MIPS), a canonical non-equilibr…
Conservative yet constitutively odd elasticity in prestressed metamaterials
Tyler A. Engstrom, Daniel M. Sussman
We introduce a design principle for mechanical metamaterials based on "odd elasticity, once removed." By revisiting classic results relating the variation of Cauchy stress and Lagr…
Spatially patterned phases in a reaction-time-symmetry-broken model of flocking
Charles R. Packard, Daniel M. Sussman
We introduce a Vicsek-like flocking model with a minimal form of time-delayed orientational interactions, in which the delays occur on a time scale that is well-separated from othe…
