Emergent polar order in nonpolar mixtures with nonreciprocal interactions
Phenomenological rules that govern the collective behavior of complex physical systems are
powerful tools because they can make concrete predictions about their universality class …

Activity waves and freestanding vortices in populations of subcritical Quincke rollers
ZT Liu, Y Shi, Y Zhao, H Chaté… - Proceedings of the …, 2021 - National Acad Sciences
Virtually all of the many active matter systems studied so far are made of units (biofilaments,
cells, colloidal particles, robots, animals, etc.) that move even when they are alone or …

Two-dimensional long-range uniaxial order in three-dimensional active fluids
A Maitra - Nature Physics, 2023 - nature.com
Elongated active units cannot spontaneously break rotation symmetry in bulk fluids to form
nematic or polar phases. This has led to the image of active suspensions as spontaneously …

Inertia drives concentration-wave turbulence in swimmer suspensions
We discover an instability mechanism in suspensions of self-propelled particles that does
not involve active stress. Instead, it is driven by a subtle interplay of inertia, swimmer motility …

Interface dynamics of wet active systems
We study the roughening of interfaces in phase-separated active suspensions on substrates.
At large length and timescales, we show that the interfacial dynamics belongs to the| q| KPZ …

Hydrodynamic theory of flocking at a solid-liquid interface: Long-range order and giant number fluctuations
We construct the hydrodynamic theory of coherent collective motion (“flocking”) at a solid-
liquid interface. The polar order parameter and concentration of a collection of “active”(self …

Using Activity to Compartmentalize Binary Mixtures
NJ Lauersdorf, E Nazockdast, D Klotsa - arxiv preprint arxiv:2407.07826, 2024 - arxiv.org
We computationally study suspensions of slow and fast active Brownian particles that have
undergone motility induced phase separation and are at steady state. Such mixtures, of …
