Kinetic and Hydrodynamic Theories of Chiral Intruder Dynamics in Nonequilibrium Baths
Raphaël Maire, Ignacio Pagonabarraga
We study the chiral dynamics of an intruder immersed in a nonequilibrium bath in two complementary limits: the dilute kinetic regime and the dense hydrodynamic regime. In the dilut…

Chiral Dynamics of an Intruder across Dilute and Hydrodynamic Regimes
Raphaël Maire, Ignacio Pagonabarraga
We introduce and simulate an analytically tractable model for an intruder of arbitrary shape in a nonequilibrium bath, with chirality originating from the bath, the intruder, or th…

Topological delocalisation of confined 3D active nematics
Louise C. Head, Pasquale Digregorio, Davide Marenduzzo +3
Defect lines in 3D active nematic systems are intriguing topological singularities whose out-of-equilibrium dynamics remain elusive in confined settings. Here, we numerically study…
