Occurrence of connected clusters in motility-induced phase-separated states of persistent active particles at zero temperature
Michael Schmiedeberg
To study the interplay of jamming, cluster formation, and motility-induced phase separation in the zero temperature limit in two dimensions, we consider a simple model system consi…
Phase Field Crystal model for particles with n-fold rotational symmetry in two dimensions
Robert F. B. Weigel, Michael Schmiedeberg
We introduce a Phase Field Crystal (PFC) model for particles with n-fold rotational symmetry in two dimensions. Our approach is based on a free energy functional that depends on th…
Investigating 3D printed Cartesian Divers
Jonas Bley, Antony Pietz, Angela Fösel +3
Despite the difficult circumstances due to the COVID-19 pandemics, physics students can tackle interesting questions that are part of physics competitions as the German Physicists'…
Active Brownian and inertial particles in disordered environments: short-time expansion of the mean-square displacement
Davide Breoni, Michael Schmiedeberg, Hartmut Löwen
We consider an active Brownian particle moving in a disordered two-dimensional energy or motility landscape. The averaged mean-square-displacement (MSD) of the particle is calculat…
Athermal Jamming vs. glassy dynamics for particles with exponentially decaying repulsive pair interaction potentials with a cutoff
Nicolas Wohlleben, Michael Schmiedeberg
We study athermal jamming as well as the thermal glassy dynamics in systems composed of spheres that interact according to repulsive interactions that exponentially decay as a func…
Oscillations due to time-delayed driving of a ball in a water jet -- a challenging problem of the International Physicists' Tournament 2019
S Michalke, A Fösel, M Schmiedeberg
The International Physicists' Tournament (IPT) 2019 dealt with 17 challenging problems. In this article, we present experimental as well as theoretical approaches exemplarily to on…
