Metastability and nucleation of bubbles in active chiral systems
Raphael Maire, Alessandro Petrini, Umberto Marini Bettolo Marconi +1
Bubbles frequently emerge in dense chiral active fluids, yet it remains unclear whether they result from an instability of the homogeneous state or from rare nucleation events with…
Curvature-driven wall accumulation in chiral active particles
Alessandro Petrini, Raphaël Maire, Umberto Marini Bettolo Marconi +1
We study a dilute system of non-motile chiral active particles confined in geometries ranging from straight channels to circular enclosures. Activity is introduced through chiral p…
Sparkling bubbles in chiral active fluids
Alessandro Petrini, Raphaël Maire, Umberto Marini Bettolo Marconi +1
We study an inertial chiral active fluid, formed by repulsive particles that transfer angular momentum through odd interactions, i.e. transverse forces. Chirality induces an inhomo…
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…
Self-assembly of quasicrystals under cyclic shear
Raphaël Maire, Andrea Plati, Frank Smallenburg +1
We investigate the self-assembly of two-dimensional dodecagonal quasicrystals driven by cyclic shear, effectively replacing thermal fluctuations with plastic rearrangements. Using…
Dynamical and structural properties of an absorbing phase transition: a case study from granular systems
Raphael Maire, Andrea Plati, Frank Smallenburg +1
We investigate the dynamical and structural properties of absorbing phase transitions (APTs) within granular systems. Specifically, we examine a model for vibrofluidized systems of…
Non-equilibrium coexistence between a fluid and a hotter or colder crystal of granular hard disks
R. Maire, A. Plati, F. Smallenburg +1
Non-equilibrium phase coexistence is commonly observed in both biological and artificial systems, yet understanding it remains a significant challenge. Unlike equilibrium systems,…
Self-assembly and non-equilibrium phase coexistence in a binary granular mixture
A. Plati, R. Maire, F. Boulogne +3
We report the experimental observation of a square crystalline phase in a vibrated binary mixture of spherical grains. This structure spontaneously forms from a disordered state, c…
Enhancing (quasi-)long-range order in a two-dimensional driven crystal
R. Maire, A. Plati
It has been recently shown that 2D systems can exhibit crystalline phases with long-range translational order showcasing a striking violation of the Hohenberg-Mermin-Wagner (HMW) t…
