Cooling mechanism controls motility-induced phase separation in inertial active liquids
Manuel Mayo, Lorenzo Caprini, María Isabel García de Soria +4
Motility-induced phase separation (MIPS) is a central collective phenomenon in active matter, theoretically established in the overdamped regime. We discover that the dynamical ori…
Circling crystals in chiral active matter with self-alignment
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
We study a crystal composed of active units governed by self-alignment and chirality. The first mechanism acts as an effective torque that aligns the particle orientation with its…
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…
Optimal area exploration by resetting active particles
Kristian Stølevik Olsen, Hartmut Löwen, Lorenzo Caprini
Identifying optimal strategies for efficient spatial exploration is crucial, both for animals seeking food and for robotic search processes, where maximizing the covered area is a…
Active particles in tunable compressible environments
Venkata Manikantha Sai Ganesh Tanuku, Isha Malhotra, Lorenzo Caprini +3
Active particles affect their environment as much as the environment affects their active motion. Here, we present an experimental system where both can be simultaneously adjusted…
Active thermodynamics of inertial chiral active gases: equation of state and edge currents
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Benno Liebchen +1
One of the most fundamental quests in the physics of active matter concerns the existence of a comprehensive theory for its macroscopic properties, i.e. an ``active thermodynamics'…
Flocking as a second-order phase transition in self-aligning active crystals
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
We study a two-dimensional crystal composed of active units governed by self-alignment. This mechanism induces a torque that aligns a particle's orientation with its velocity and l…
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…
Self-alignment and anti-self-alignment suppress motility-induced phase separation in active systems
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
In this article, we investigate the impact of self-alignment and anti-self-alignment on collective phenomena in dense active matter. These mechanisms correspond to effective torque…
Self-sustained frictional cooling in active matter
Alexander P. Antonov, Marco Musacchio, Hartmut Löwen +1
Cooling processes in nature are typically generated by external contact with a cold reservoir or bath. According to the laws of thermodynamics, the final temperature of a system is…
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…
