How does a thermal binary crystal break under shear?
Tobias Horn, Hartmut Löwen
When exposed to strong shearing, the particles in a crystal will rearrange and ultimately, the crystal will break by forming large nonaffine defects. Even for the initial stage of…
Liquid pair correlations in four spatial dimensions: Theory versus simulation
M. Heinen, J. Horbach, H. Löwen
Using liquid integral equation theory, we calculate the pair correlations of particles that interact via a smooth repulsive pair potential in d = 4 spatial dimensions. We discuss t…
Motion of two micro-wedges in a turbulent bacterial bath
Andreas Kaiser, Andrey Sokolov, Igor S. Aranson +1
The motion of a pair of micro-wedges ("carriers") in a turbulent bacterial bath is explored using computer simulations with explicit modeling of the bacteria and experiments. The o…
Can the self-propulsion of anisotropic microswimmers be described by using forces and torques?
Borge ten Hagen, Raphael Wittkowski, Daisuke Takagi +3
The self-propulsion of artificial and biological microswimmers (i.e., active colloidal particles) has often been modelled by using a force and a torque entering into the overdamped…
Dynamical density functional theory for the diffusion of injected Brownian particles
H. Löwen, M. Heinen
While the theory of diffusion of a single Brownian particle in confined geometries is well-established by now, we discuss here the theoretical framework necessary to generalize the…
Gravitaxis of asymmetric self-propelled colloidal particles
Borge ten Hagen, Felix Kümmel, Raphael Wittkowski +3
Many motile microorganisms adjust their swimming motion relative to the gravitational field and thus counteract sedimentation to the ground. This gravitactic behavior is often the…
Active colloidal suspensions: Clustering and phase behavior
Julian Bialké, Thomas Speck, Hartmut Löwen
We review recent experimental, numerical, and analytical results on active suspensions of self-propelled colloidal beads moving in (quasi) two dimensions. Active colloids form part…
Reply to Comment on "Circular Motion of Asymmetric Self-Propelling Particles"
Felix Kümmel, Borge ten Hagen, Raphael Wittkowski +6
In a Comment [Phys. Rev. Lett. 113, 029801 (2014)] on our Letter on self-propelled asymmetric particles [Phys. Rev. Lett. 110, 198302 (2013); arXiv:1302.5787], Felderhof claims tha…
Structural control of elastic moduli in ferrogels and the importance of non-affine deformations
Giorgio Pessot, Peet Cremer, Dmitry Y. Borin +3
One of the central appealing properties of magnetic gels and elastomers is that their elastic moduli can reversibly be adjusted from outside by applying magnetic fields. The impact…
Magnetomechanical response of bilayered magnetic elastomers
Elshad Allahyarov, Andreas M. Menzel, Lei Zhu +1
Magnetic elastomers are appealing materials from an application point of view: they combine the mechanical softness and deformability of polymeric substances with the addressabilit…
Unusual swelling of a polymer in a bacterial bath
Andreas Kaiser, Hartmut Löwen
The equilibrium structure and dynamics of a single polymer chain in a thermal solvent is by now well-understood in terms of scaling laws. Here we consider a polymer in a bacterial…
Tunable dynamic response of magnetic gels: impact of structural properties and magnetic fields
Mitsusuke Tarama, Peet Cremer, Dmitry Y. Borin +3
Ferrogels and magnetic elastomers feature mechanical properties that can be reversibly tuned from outside through magnetic fields. Here we concentrate on the question how their dyn…
Growth modes of quasicrystals
C. V. Achim, M. Schmiedeberg, H. Löwen
The growth of quasicrystals, i.e., aperiodic structures with long-range order, seeded from the melt is investigated using a dynamical phase field crystal model. Depending on the th…
Transport powered by bacterial turbulence
Andreas Kaiser, Anton Peshkov, Andrey Sokolov +3
We demonstrate that collective turbulent-like motion in a bacterial bath can power and steer directed transport of mesoscopic carriers through the suspension. In our experiments an…
Active crystals and their stability
Andreas M. Menzel, Takao Ohta, Hartmut Löwen
A recently introduced active phase field crystal model describes the formation of ordered resting and traveling crystals in systems of self-propelled particles. Increasing the acti…
A deformable microswimmer in a swirl: capturing and scattering dynamics
Mitsusuke Tarama, Andreas M. Menzel, Hartmut Löwen
Inspired by the classical Kepler and Rutherford problem, we investigate an analogous set-up in the context of active microswimmers: the behavior of a deformable microswimmer in a s…
