DOI: 10.1002/smll.202300817
Abstract: Due to the intrinsically complex non-equilibrium behavior of the constituents of active matter systems, a comprehensive understanding of their collective properties is a challenge that requires systematic bottom-up characterization of the individual components and their… read more here.

DOI: 10.1016/j.cma.2021.113806
Abstract: Abstract We consider the numerical approximations to simulate the active colloids dynamic process. One linear, decoupled, mass-preserving scheme is proposed, in which mass-preserving characteristic finite element method is utilized for the density equation of active… read more here.

DOI: 10.1038/s41467-020-16161-4
Abstract: Many animal species organise into disordered swarms, polarised flocks or swirls to protect from predators or optimise foraging. Previous studies suggest that such collective states are related to a critical point, which could explain their… read more here.

DOI: 10.1039/d2sm00957a
Abstract: Many motile microorganisms communicate with each other and their environments via chemical signaling which leads to long-range interactions mediated by self-generated chemical gradients. However, consequences of the interplay between crowding and chemotactic interactions on their… read more here.

DOI: 10.1103/physrevlett.118.268001
Abstract: We introduce a representative minimal model for phoretically interacting active colloids. Combining kinetic theory, linear stability analyses, and a general relation between self-propulsion and phoretic interactions in autodiffusiophoretic and autothermophoretic Janus colloids collapses the parameter… read more here.

DOI: 10.3389/fchem.2022.803906
Abstract: Catalytic activity of the colloids and chemotactic response to gradients of the chemicals in the solution leads to effective interaction between catalytic colloids. In this paper, we simulate mixtures of active and passive colloids via… read more here.
