Pore-scale distribution and transport of active particles in a two-dimensional lattice
Akhil Varma, David Saintillan
Suspensions of motile microswimmers such as bacteria and other active colloids frequently encounter porous environments where obstacles and complex shear flows strongly influence t…
Collective dynamics of active suspensions on curved viscous interfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Self-propelled particles can navigate complex environments, including viscous fluid interfaces with curved geometries. In this work, we study the emergent dynamics of a suspension…
Reversibility, Chaos, and Attractors in Periodically Sheared Elastic Filaments
Francesco Bonacci, Brato Chakrabarti, Olivia du Roure +2
The dynamics of filaments in flow are central to understanding a wide range of biological and soft-matter systems, yet their behavior under time-dependent forcing remains poorly un…
Active Hydrodynamic Theory of Euchromatin and Heterochromatin
S. Alex Rautu, Alexandra Zidovska, David Saintillan +1
The genome contains genetic information essential for cell's life. The genome's spatial organization inside the cell nucleus is critical for its proper function including gene regu…
Stability of co-annular active and passive confined fluids
Tanumoy Dhar, Michael J. Shelley, David Saintillan
The translation and shape deformations of a passive viscous Newtonian droplet immersed in an active nematic liquid crystal under circular confinement are analyzed using a linear st…
Hydrodynamics converts chiral flagellar rotation into contactless actuation of microdiscs
Daniel Grober, Tanumoy Dhar, David Saintillan +1
Motile bacteria are a wonder of nature's engineering: microscopic engines that transduce biochemical energy into the work they require to explore their environment. This added ener…
