A unified field theory of topological defects and non-linear local excitations
Vidar Skogvoll, Jonas Rønning, Marco Salvalaglio +1
Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively descr…
Mechanical transmission of rotational motion between molecular-scale gears
H. -H. Lin, A. Croy, R. Gutierrez +2
Manipulating and coupling molecule gears is the first step towards realizing molecular-scale mechanical machines. Here, we theoretically investigate the behavior of such gears usin…
Topological and geometrical quantities in active cellular structures
Dennis Wenzel, Simon Praetorius, Axel Voigt
Topological and geometrical properties and the associated topological defects find a rapidly growing interest in studying the interplay between mechanics and the collective behavio…
A microscopic field theoretical approach for binary mixtures of active and passive particles
Francesco Alaimo, Axel Voigt
We consider a phase field crystal modeling approach for binary mixtures of interacting active and passive particles. The approach allows to describe generic properties for such sys…
Active crystals on a sphere
Simon Praetorius, Axel Voigt, Raphael Wittkowski +1
Two-dimensional crystals on curved manifolds exhibit nontrivial defect structures. Here, we consider "active crystals" on a sphere, which are composed of self-propelled colloidal p…
Nematic liquid crystals on curved surfaces - a thin film limit
Ingo Nitschke, Michael Nestler, Simon Praetorius +2
We consider a thin film limit of a Landau-de Gennes Q-tensor model. In the limiting process we observe a continuous transition where the normal and tangential parts of the Q-tensor…
