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…
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…
Time scales of inertial motion in the collective dynamics of underdamped active phase field crystal systems
Dominic Arold, Michael Schmiedeberg
Many active matter systems, mostly on the microscopic scale, are well approximated as overdamped, meaning that any inertial momentum is immediately dissipated by the environment. O…
Mean field approach of dynamical pattern formation in underdamped active matter with short-ranged alignment and distant anti-alignment interactions
Dominic Arold, Michael Schmiedeberg
Many active matter systems, especially on the microscopic scale, are well approximated as overdamped, meaning that any inertial momentum is immediately dissipated by the environmen…
Phasonic Diffusion and Self-confinement of Decagonal Quasicrystals in Hyperspace
Johannes Hielscher, Miriam Martinsons, Michael Schmiedeberg +1
We introduce a novel simulation method that is designed to explore fluctuations of the phasonic degrees of freedom in decagonal colloidal quasicrystals. Specifically, we attain and…
Event-chain Monte Carlo simulations of the liquid to solid transition of two-dimensional decagonal colloidal quasicrystals
M. Martinsons, J. Hielscher, S. C. Kapfer +1
In event-chain Monte Carlo simulations we model colloidal particles in two dimensions that interact according to an isotropic short-ranged pair potential which supports the two typ…
Energy landscape description of the clustering transition for active soft spheres
Moumita Maiti, Michael Schmiedeberg
For a system consisting of active soft spheres in three dimensions, we study the transition from a fluid where overlaps between particles can only occur for a short time after a co…
The thermal jamming transition of soft harmonic disks in two dimensions
Moumita Maiti, Michael Schmiedeberg
By exploring the properties of the energy landscape of a bidisperse system of soft harmonic disks in two dimensions we determine the thermal jamming transition. To be specific, we…
Temperature dependence of the transition packing fraction of thermal jamming in a harmonic soft sphere system
Moumita Maiti, Michael Schmiedeberg
The glassy dynamics of soft harmonic spheres is often mapped onto the dynamics of hard spheres by considering an effective diameter for the soft particles and therefore an effectiv…
Self-assembly of complex structures in colloid-polymer mixtures
Erdal C. Oğuz, Aleksandar Mijailović, Michael Schmiedeberg
If particles interact according to isotropic pair potentials that favor multiple length scales, in principle a large variety of different complex structures can be achieved by self…
Ergodicity breaking transition in a glassy soft sphere system at small but non-zero temperatures
Moumita Maiti, Michael Schmiedeberg
While the glass transition at non-zero temperature seems to be hard to access for experimental, theoretical, or simulation studies, jamming at zero temperature has been explored in…
Anisotropy and memory during cage breaking events close to a wall
Matthias Kohl, Andreas Härtel, Michael Schmiedeberg
The slow dynamics in a glassy hard-sphere system is dominated by cage breaking events, i.e., rearrangements where a particle escapes from the cage formed by its neighboring particl…
Horizons and free path distributions in quasiperiodic Lorentz gases
Atahualpa S. Kraemer, Michael Schmiedeberg, David P. Sanders
We study the structure of quasiperiodic Lorentz gases, i.e., particles bouncing elastically off fixed obstacles arranged in quasiperiodic lattices. By employing a construction to e…
Anisotropic pair correlations in binary and multicomponent hard-sphere mixtures in the vicinity of a hard wall: A combined density functional theory and simulation study
Andreas Härtel, Matthias Kohl, Michael Schmiedeberg
The fundamental measure approach to classical density functional theory has been shown to be a powerful tool to predict various thermodynamic properties of hard-sphere systems. We…
Brownian particles on rough substrates: Relation between the intermediate subdiffusion and the asymptotic long-time diffusion
Richard D. L. Hanes, Michael Schmiedeberg, Stefan U. Egelhaaf
Brownian particles in random potentials show an extended regime of subdiffusive dynamics at intermediate times. The asymptotic diffusive behavior is often established at very long…
