Self-organized flows in phase-synchronizing active fluids
Brato Chakrabarti, Michael J. Shelley, Sebastian Fürthauer
Many active biological particles, such as swimming microorganisms or motor-proteins, do work on their environment by going though a periodic sequence of shapes. Interactions betwee…
Thermodynamically consistent coarse-graining of polar active fluids
Scott Weady, David B. Stein, Michael J. Shelley
We introduce a closure model for coarse-grained kinetic theories of polar active fluids. Based on a quasi-equilibrium approximation of the particle distribution function, the model…
Towards the cellular-scale simulation of motor-driven cytoskeletal assemblies
Wen Yan, Saad Ansari, Adam Lamson +3
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…
A multiscale biophysical model gives quantized metachronal waves in a lattice of cilia
Brato Chakrabarti, Sebastian Fürthauer, Michael J. Shelley
Motile cilia are slender, hair-like cellular appendages that spontaneously oscillate under the action of internal molecular motors and are typically found in dense arrays. These ac…
How crosslink numbers shape the large-scale physics of cytoskeletal materials
Sebastian Fürthauer, Michael J. Shelley
Cytoskeletal networks are the main actuators of cellular mechanics, and a foundational example for active matter physics. In cytoskeletal networks, motion is generated on small sca…
Hyperuniformity and phase enrichment in vortex and rotor assemblies
Naomi Oppenheimer, David B. Stein, Matan Yah Ben Zion +1
Ensembles of particles rotating in a two-dimensional fluid can exhibit chaotic dynamics yet develop signatures of hidden order. Such "rotors" are found in the natural world spannin…
