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…
Connecting anomalous elasticity and sub-Arrhenius structural dynamics in a cell-based model
Chengling Li, Matthias Merkel, Daniel M. Sussman
Understanding the structural dynamics of many-particle glassy systems remains a key challenge in statistical physics. Over the last decade, glassy dynamics has also been reported i…
Banded phases in topological flocks
Charles R. Packard, Daniel M. Sussman
Flocking phase transitions found in models of polar active matter are paradigmatic examples of active phase transitions in soft matter. An interesting specialization of flocking mo…
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…
Scale-dependent sharpening of interfacial fluctuations in shape-based models of dense cellular sheets
Haicen Yue, Charles R. Packard, Daniel M. Sussman
The properties of tissue interfaces -- between separate populations of cells, or between a group of cells and its environment -- has attracted intense theoretical, computational, a…
curvedSpaceSim: A framework for simulating particles interacting along geodesics
Toler H. Webb, Daniel M. Sussman
A large number of powerful, high-quality, and open-source simulation packages exist to efficiently perform molecular dynamics simulations, and their prevalence has greatly accelera…
Glassy Dynamics in Models of Confluent Tissue with Mitosis and Apoptosis
Michael Czajkowski, Daniel M. Sussman, M. Cristina Marchetti +1
Recent work on particle-based models of tissues has suggested that any finite rate of cell division and cell death is sufficient to fluidize an epithelial tissue. At the same time,…
Small-scale demixing in confluent biological tissues
Preeti Sahu, Daniel M. Sussman, Matthias Rubsam +7
Surface tension governed by differential adhesion can drive fluid particle mixtures to sort into separate regions, i.e., demix. Does the same phenomenon occur in confluent biologic…
