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…
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…
Dynamical density functional theory for dense odd-diffusive fluids
Iman Abdoli, René Wittmann, Hartmut Löwen
Odd diffusion breaks time-reversal symmetry in overdamped systems through transverse probability currents while preserving equilibrium steady states. In this work, we develop a dyn…
Quadrupolar gyration of a Brownian particle in a confining ring
Iman Abdoli, Hartmut Löwen
We develop a minimal theoretical model that reveals a structured steady-state flux field with four alternating local circulation, a phenomenon we refer to as quadrupolar gyration.…
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…
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…
