The 2019 Motile Active Matter Roadmap
Gerhard Gompper, Roland G. Winkler, Thomas Speck +34
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…
Binary crystals in two-dimensional two-component Yukawa mixtures
Lahcen Assoud, Rene Messina, Hartmut Loewen
The zero-temperature phase diagram of binary mixtures of particles interacting via a screened Coulomb pair potential is calculated as a function of composition and charge ratio. Th…
A circle swimmer at low Reynolds number
Rodrigo Ledesma-Aguilar, Hartmut Loewen, Julia M. Yeomans
Swimming in circles occurs in a variety of situations at low Reynolds number. Here we propose a simple model for a swimmer that undergoes circular motion, generalising the model of…
Fluid phase separation inside a static periodic field: an effectively two-dimensional critical phenomenon
Richard Vink, Tim Neuhaus, Hartmut Loewen
When a fluid with a bulk liquid-vapor critical point is placed inside a static external field with spatial periodic oscillations in one direction, the bulk critical point splits in…
Collapse of Telechelic Star Polymers to Water-Melon Structures
Federica Lo Verso, Christos N. Likos, Christian Mayer +1
Conformational properties of star-shaped polymer aggregates that carry attractive end-groups, called telechelic star polymers, are investigated by simulation and analytical variati…
Reentrant transitions in colloidal or dusty plasma bilayers
Rene Messina, Hartmut Loewen
The phase diagram of crystalline bilayers of particles interacting via a Yukawa potential is calculated for arbitrary screening lengths and particle densities. Staggered rectangula…
Multiple glass transitions in star polymer mixtures: Insights from theory and simulations
Christian Mayer, Francesco Sciortino, Christos N. Likos +3
The glass transition in binary mixtures of star polymers is studied by mode coupling theory and extensive molecular dynamics computer simulations. In particular, we have explored v…
Structure and dynamics of a glass-forming binary complex plasma with non-reciprocal interaction
Yi-Fei Lin, Alexei Ivlev, Hartmut Loewen +2
In this letter, we present the first numerical study on the structural and dynamical properties of a quasi-two-dimensional (q2D) binary complex plasma with Langevin dynamics simula…
