Self-reconfiguring colloidal active matter
Stefania Ketzetzi, Lorenzo Caprini, Vivien Willems +3
Cells and microorganisms employ dynamic shape changes to enable steering and avoidance for efficient spatial exploration and collective organization. In contrast, active colloids,…
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…
Spontaneous self-wrapping in chiral active polymers
Lorenzo Caprini, Iman Abdoli, Umberto Marini Bettolo Marconi +1
Biological organisms often have elongated, flexible structures with some degree of chirality in their bodies or movements. In nature, these organisms frequently take advantage of s…
Bubble phase induced by odd interactions
Lorenzo Caprini, Umberto Marini Bettolo Marconi
We study a repulsive thermal system governed by odd interactions. The interplay between oddness and inertia induces a non-equilibrium phase transition from a homogeneous to a non-h…
How to define temperature in active systems?
Lukas Hecht, Lorenzo Caprini, Hartmut Löwen +1
We are used to measure temperature with a thermometer and we know from everyday life that different types of thermometers measure the same temperature. This experience can be based…
Dynamical clustering and wetting phenomena in inertial active matter
Lorenzo Caprini, Davide Breoni, Anton Ldov +2
Dynamical clustering represents a characteristic feature of active matter consisting of self-propelled agents that convert energy from the environment into mechanical motion. At th…
Self-reverting vortices in chiral active matter
Lorenzo Caprini, Benno Liebchen, Hartmut Löwen
There is currently a strong interest in the collective behavior of chiral active particles that can propel and rotate themselves. In the presence of alignment interactions for many…
Inertial active matter with Coulomb friction
Alexander P. Antonov, Lorenzo Caprini, Anton Ldov +2
Friction is central to the motion of active (self-propelled) objects such as bacteria, animals, and robots. While in a viscous fluid friction is described by Stokes's law, objects…
Active fluctuations in the harmonic chain: phonons, entropons and velocity correlations
Umberto Marini Bettolo Marconi, Hartmut Löwen, Lorenzo Caprini
Non-equilibrium random fluctuations of non-thermal nature are a salient feature of active matter. In this work, we consider the collective excitations of active systems at high den…
