A particle-resolved rheological study of chirality transfer and odd transport
Rémi Goerlich, Alexander P. Antonov, Kristian Stølevik Olsen +4
Chirality, or the breaking of mirror symmetry, appears across all scales in nature, from molecular conformations to the dynamics of bacterial collectives. Environments composed of…
Self-propulsion protocols for swift non-equilibrium state transitions and enhanced cooling in active systems
Kristian Stølevik Olsen, Hartmut Löwen
A control framework is proposed for inducing non-equilibrium state transitions in confined active matter, where the statistics of self-propulsion serve as the only control paramete…
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…
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…
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…
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,…
