Kinetic Theory of Chiral Active Disks: Odd Transport and Torque Density
Raphael Maire, Alessandro Petrini, Umberto Marini Bettolo Marconi +1
The paper builds a kinetic theory for a two‑dimensional gas of hard disks that receive a transverse impulse on collision, creating chiral active behavior and resulting in odd trans…
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…
Active Gaussian Network Model: a non-equilibrium description of protein fluctuations and allosteric behavior
Giulio Costantini, Lorenzo Caprini, Umberto Marini Bettolo Marconi +1
Understanding the link between structure and function in proteins is fundamental in molecular biology and proteomics. A central question in this context is whether allostery - wher…
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…
