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…

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…

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…
