Emergent hydrodynamics of chiral active fluids: vortices, bubbles and odd diffusion
Umberto Marini Bettolo Marconi, Alessandro Petrini, Raphaël Maire +1
Starting from a microscopic multiparticle Langevin equation, we systematically derive a hydrodynamic description in terms of density and momentum fields for chiral active particles…
Modeling chiral active particles: from circular motion to odd interactions
Lorenzo Caprini, Alessandro Petrini, Umberto Marini Bettolo Marconi
In this paper, we discuss microscopic models for chiral active particles, i.e., rotating active units that exhibit circular or spinning motion. While non-chiral active particles ar…
Odd Active Solids: Vortices, Velocity Oscillations and Dissipation-Free Modes
Lorenzo Caprini, Umberto Marini Bettolo Marconi
A wide range of physical and biological systems, including colloidal magnets, granular spinners, and starfish embryos, are characterized by strongly rotating units that give rise t…
Spontaneous generation of angular momentum in chiral active crystals
Umberto Marini Bettolo Marconi, Lorenzo Caprini
We study a two-dimensional chiral active crystal composed of underdamped chiral active particles. These particles, characterized by intrinsic handedness and persistence, interact v…
Spatial velocity correlations in inertial systems of Active Brownian Particles
Lorenzo Caprini, Umberto Marini Bettolo Marconi
Recently, it has been discovered that systems of Active Brownian particles (APB) at high density organise their velocities into coherent domains showing large spatial structures in…
Inertial self-propelled particles
Lorenzo Caprini, Umberto Marini Bettolo Marconi
We study a self-propelled particle moving in a solvent with the active Ornstein Uhlenbeck dynamics in the underdamped regime to evaluate the influence of the inertia. We focus on t…
