We review the state of the art of active fluids with particular attention to hydrodynamic
continuous models and to the use of Lattice Boltzmann Methods (LBM) in this field. We …

We study binary mixtures of small active and big passive athermal particles interacting via
soft repulsive forces on a frictional substrate. Athermal self propelled particles are known to …

Active systems are self-driven systems that live, or function, far from thermodynamic
equilibrium. A paradigmatic example is provided by a suspension of interacting self-motile …

We study the stationary dynamics of an active interacting Brownian particle system. We
measure the violations of the fluctuation dissipation theorem, and the corresponding …

We study the statistics, in stationary conditions, of the work W τ done by the active force in
different systems of self-propelled particles in a time τ. We show the existence of a critical …

We study a suspension of active dumbbells of variable density, as a minimal example of an
active polar fluid. As in a fluid of spherical swimmers, we find that motility triggers a …

We numerically study the dynamics and the phases of self-propelled disk-shaped particles
of different sizes with soft repulsive potential in two dimensions. Size diversity is introduced …

We demonstrate that there is a macroscopic coexistence between regions with hexatic order
and regions in the liquid or gas phase over a finite interval of packing fractions in active …

The collective behavior of chemically propelled sphere-dimer motors made from linked
catalytic and noncatalytic spheres in a quasi-two-dimensional confined geometry is studied …

We review recent advances in the design, synthesis, and modeling of active fluids. Active
fluids have been at the center of many technological innovations and theoretical advances …
