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 models concerns a ``topological'' vs ``metric'' choice by which agents a

Scale-dependent sharpening of interfacial fluctuations in shape-based models of dense cellular sheets

Autor: Yue, Haicen, Packard, Charles R., Sussman, Daniel M.

The properties of tissue interfaces -- between separate populations of cells, or between a group of cells and its environment -- has attracted intense theoretical, computational, and experimental study. Recent work on shape-based models inspired by d

Self-organized vortex phases and hydrodynamic interactions in Bos taurus sperm cells

Autor: Packard, Charles R., Unnikrishnan, Shobitha, Phuyal, Shiva, Cheong, Soon Hon, Manning, M. Lisa, Tung, Chih-Kuan, Sussman, Daniel M.

Flocking behavior is observed in biological systems from the cellular to super-organismal length scales, and the mechanisms and purposes of this behavior are objects of intense interest. In this paper, we study the collective dynamics of bovine sperm

Non-reciprocal forces and exceptional phase transitions in metric and topological flocks

Autor: Packard, Charles, Sussman, Daniel M.

Many models of flocking involve alignment rules based on the mean orientation of neighboring particles, which we show introduces microscopic non-reciprocal interactions. In the absence of this microscopic non-reciprocity an exceptional phase transiti
