Cluster dynamics in macroscopic photoactive particles
Sára Lévay, Axel Katona, Hartmut Löwen +2
We present an experimental study on the collective behavior of macroscopic self-propelled particles that are externally excited by light. This property allows testing the system re…
A Hitchhiker's Guide To Active Motion
Tobias Plasczyk, Paul A. Monderkamp, Hartmut Löwen +1
Intelligent decisions in response to external informative input can allow organisms to achieve their biological goals while spending very little of their own resources. In this pap…
Confined active particles with spatially dependent Lorentz force: an odd twist to the "best Fokker-Planck approximation"
René Wittmann, Iman Abdoli, Abhinav Sharma +1
We derive a version of the so-called "best Fokker-Planck approximation" (BFPA) to describe the spatial properties of interacting active Ornstein-Uhlenbeck particles (AOUPs) in arbi…
Precisely controlled colloids: A playground for path-wise non-equilibrium physics
Cai Dieball, Yasamin Mohebi Satalsari, Angel B. Zuccolotto-Bernezb +3
We investigate path-wise observables in experiments on driven colloids in a periodic light field to dissect selected intricate transport features, kinetics, and transition-path tim…
Cybloids Creation and Control of Cybernetic Colloids
Debasish Saha, Sonja Tarama, Hartmut Löwen +1
Colloids play an important role in fundamental science as well as in nature and technology. They have had a strong impact on the fundamental understanding of statistical physics. F…
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…
