Scaling behavior in non-reciprocal and odd conserved dynamics near criticality
Martin Kjøllesdal Johnsrud, Giulia Pisegna, Ramin Golestanian
In recent years, non-reciprocity has been explored as a ubiquitous manifestation of non-equilibrium activity at the microscopic scales for various active matter systems, from mixtu…
Mixing induced by microswimmers as probed by mutual information
Yihong Shi, Yuto Hosaka, Andrej Vilfan +1
We investigate fluid mixing induced by microswimmers using mutual information as a global, information-theoretic measure of mixing efficiency. For a two-dimensional squirmer model…
Controlled Chemical Signaling between Enzymatic Nanomotors
Shuqin Chen, Giorgio Lovato, Oriol Jutglar Soler +3
The coordinated interactions between organisms enhance collective functionality, a feature that artificial systems such as enzymatic nanomotors seek to replicate. A key objective,…
Self-diffusiophoretic propulsion in wedge confinement: The role of phoretic interactions
Abdallah Daddi-Moussa-Ider, Ramin Golestanian
We investigate the self-diffusiophoretic motion of a catalytically active spherical particle confined within a wedge-shaped domain. Using the Fourier-Kontorovich-Lebedev transform,…
Self-phoretic colloids in chiral active fluids
Michalis Chatzittofi, Yuto Hosaka, Andrej Vilfan +1
Autonomous and driven transport in chiral active fluids have been shown to exhibit features that cannot be accommodated within the classical formulation of fluid mechanics, due to…
Emergent single-species non-reciprocity from bistable chemical dynamics
Jakob Metson, Ramin Golestanian
The appearance of emergent symmetries in complex systems with components that can form composite units provides us with opportunities for design and control of exotic phase behavio…
