Emergent phenomena in chiral active matter

J Mecke, JO Nketsiah, R Li, Y Gao - National Science Open, 2024 - nso-journal.org
In recent years, there has been growing interest in the study of chiral active materials, which
consist of building blocks that show active dynamics featuring chiral symmetry breaking, eg …

Lorentz reciprocal theorem in fluids with odd viscosity

Y Hosaka, R Golestanian, A Vilfan - Physical Review Letters, 2023 - APS
The Lorentz reciprocal theorem—that is used to study various transport phenomena in
hydrodynamics—is violated in chiral active fluids that feature odd viscosity with broken time …

Odd elasticity of a catalytic micromachine

A Kobayashi, K Yasuda, K Ishimoto, LS Lin… - Journal of the Physical …, 2023 - journals.jps.jp
We perform numerical simulations of a model micromachine driven by catalytic chemical
reactions. Our model includes a mechano-chemical coupling between the structural …

Chirotactic response of microswimmers in fluids with odd viscosity

Y Hosaka, M Chatzittofi, R Golestanian, A Vilfan - Physical Review Research, 2024 - APS
Odd viscosity is a property of chiral active fluids with broken time-reversal and parity
symmetries. We show that the flow of such a fluid around a rotating axisymmetric body is …

Slip-induced odd viscous flow past a cylinder

R Lier - Physical Review Fluids, 2024 - APS
Odd viscosity is a transport coefficient that can occur when fluids experience breaking of
parity and time-reversal symmetry. Previous knowledge indicates that cylinders in …

Hydrodynamics of an odd active surfer in a chiral fluid

Y Hosaka, R Golestanian… - New Journal of …, 2023 - iopscience.iop.org
We theoretically and computationally study the low-Reynolds-number hydrodynamics of a
linear active microswimmer surfing on a compressible thin fluid layer characterized by an …

Force dipole interactions in tubular fluid membranes

S Jain, R Samanta - Physics of Fluids, 2023 - pubs.aip.org
We construct viscous fluid flow sourced by a force dipole embedded in a cylindrical fluid
membrane, coupled to external embedding fluids. We find analytic expressions for the flow …

Probe particles in odd active viscoelastic fluids: How activity and dissipation determine linear stability

C Duclut, S Bo, R Lier, J Armas, P Surówka, F Jülicher - Physical Review E, 2024 - APS
Odd viscoelastic materials are constrained by fewer symmetries than their even
counterparts. The breaking of these symmetries allows these materials to exhibit different …
