The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

Mathematical models are indispensable for disentangling the interactions through which
biological components work together to generate the forces and flows that position, mix, and …

The cytoskeleton–a collection of polymeric filaments, molecular motors, and crosslinkers–is
a foundational example of active matter, and in the cell assembles into organelles that guide …

The interaction of fibers in a viscous (Stokes) fluid plays a crucial role in industrial and
biological processes, such as sedimentation, rheology, transport, cell division, and …

Every animal cell is filled with a cytoskeleton, a dynamic gel made of inextensible fibers,
such as microtubules, actin fibers, and intermediate filaments, all suspended in a viscous …

Predicting the dynamic behaviors of particles in suspension subject to hydrodynamic
interaction (HI) and external drive can be critical for many applications. By harvesting …

Understanding the behaviors of suspension drops (particle swarms) as they settle in a
viscous fluid holds significant importance across various applications. Due to hydrodynamic …

Living matter moves, deforms, and organizes itself. In cells this is made possible by networks
of polymer filaments and crosslinking molecules that connect filaments to each other and …

We perform detailed computational and experimental measurements of the driven dynamics
of a dense, uniform suspension of sedimented microrollers driven by a magnetic field …

We introduce a closure model for coarse-grained kinetic theories of polar active fluids.
Based on a quasiequilibrium approximation of the particle distribution function, the model …
