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…
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…
Tunable glassy dynamics in models of dense cellular tissue
Helen S. Ansell, Chengling Li, Daniel M. Sussman
Observations of glassy dynamics in experiments on confluent cellular tissue have inspired a wealth of computational and theoretical research to model their emergent collective beha…
Twisted loxodromes in spindle-shaped polymer nematics
Helen S. Ansell, Randall D. Kamien
We develop an energetic model that captures the twisting behavior of spindle-shaped polymer microparticles with nematic ordering, which display remarkably different twisting behavi…
The Topological Origin of the Peierls-Nabarro Barrier
Brook J. Hocking, Helen S. Ansell, Randall D. Kamien +1
Crystals and other condensed matter systems described by density waves often exhibit dislocations. Here we show, by considering the topology of the ground state manifolds (GSMs) of…
Transitions between phyllotactic lattice states in curved geometries
H. S. Ansell, A. A. Tomlinson, N. K. Wilkin
Phyllotaxis, the regular arrangement of leaves or other lateral organs in plants including pineapples, sunflowers and some cacti, has attracted scientific interest for centuries. M…
Threading the spindle: a geometric study of chiral liquid crystal polymer microparticles
H. S. Ansell, D. S. Kim, R. D. Kamien +2
Polymeric particles are strong candidates for designing artificial materials capable of emulating the complex twisting-based functionality observed in biological systems. In this l…
