Jerky Motion of Active Granular Particles
Alexander P. Antonov, Marco Musacchio, Hartmut Löwen +1
Abrupt transitions between rest and motion can render the standard Newtonian description -- based on position, velocity, and acceleration -- incomplete, requiring higher-order deri…
Magnetic active matter across scales
Francisca Guzmán-Lastra, Margaret Rosenberg, Marco Musacchio +2
Magnetic interactions provide a versatile and powerful tool for controlling and organizing active matter, where individual units continuously consume energy to drive autonomous mot…
Fluidization induced by Magnetic Interactions in Confined Active Matter
Marco Musacchio, Markus Felber, Matteo Paoluzzi +3
We investigate magnetic active matter in confined geometries using both experiments with magnetic toy robots Hexbugs and simulations of elongated magnetic active Brownian particles…
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…
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…
