Analytical response functions for a compressible thin fluid layer with odd viscosity *

Published on 2026-06-09 by Abdallah Daddi-Moussa-Ider, Yuto Hosaka and Shigeyuki Komura @IOP SCIENCE

Abstract: Fluids composed of chiral active components can exhibit odd viscosity, a property that breaks time-reversal and parity symmetries. We investigate the hydrodynamic response to monopole and dipole singularities in a compressible thin fluid layer with odd viscosity, supported by a conventional lubrication layer. Using the two-dimensional Green’s function in Fourier space, we derive analytical solutions for the flow and pressure fields. These solutions provide a detailed description of the hydrody[...]


Our summary: This study explores the hydrodynamic response of a compressible thin fluid layer with odd viscosity. Analytical solutions for flow and pressure fields are derived using the two-dimensional Green’s function in Fourier space. The findings enhance understanding of particle dynamics and collective behavior in chiral microfluidic systems.

vortices, bubbles and odd diffusion

Published on 2026-05-29 by Umberto Marini Bettolo Marconi, Alessandro Petrini, Raphael Maire and Lorenzo Caprini @IOP SCIENCE

Abstract: Starting from a microscopic multiparticle Langevin equation, we obtain a hydrodynamic description in terms of density and momentum fields for chiral active particles interacting via standard repulsive and nonlocal odd forces. These odd interactions are reciprocal but non-conservative: they are non-potential forces, as they act perpendicular to the vector joining any pair of particles. As a result, the torques that two particles exert on one another are non-reciprocal. The ensuing macroscopic con[...]


Our summary: This study develops a hydrodynamic model for chiral active particles under non-conservative odd forces. It predicts phenomena such as odd diffusivity, bubble-like structures, and vortices. The findings align with numerical simulations and suggest experimental validation in granular and microbial systems.
