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…

Cluster tomography in percolation

Helen S. Ansell, Samuel J. Frank, István A. Kovács

In cluster tomography, we propose measuring the number of clusters intersected by a line segment of length across a finite sample. As expected, the leading order of $N(\…

Unveiling universal aspects of the cellular anatomy of the brain

Helen S. Ansell, István A. Kovács

Recent cellular-level volumetric brain reconstructions have revealed high levels of anatomic complexity. Determining which structural aspects of the brain to focus on, especially w…

Multipartite Entanglement in the Random Ising Chain

Jay S. Zou, Helen S. Ansell, István A. Kovács

Quantifying entanglement of multiple subsystems is a challenging open problem in interacting quantum systems. Here, we focus on two subsystems of length separated by a dista…

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…
