Surface Minkowski tensors to characterize shapes on curved surfaces
Lea Happel, Hanne Hardering, Simon Praetorius +1
We introduce surface Minkowski tensors to characterize rotational symmetries of shapes embedded in curved surfaces. The definition is based on a modified vector transport of the sh…
Suppression of hyperuniformity in hydrodynamic scalar active field theories
Nadia Bihari Padhan, Axel Voigt
The coarsening dynamics at late times in phase-separating systems lead to universally hyperuniform patterns. This is well known for scalar field theories, such as the Cahn-Hilliard…
Shape Evolution of Fluid Deformable Surfaces under Active Geometric Forces
Maik Porrmann, Axel Voigt
Models for fluid deformable surfaces provide valid theories to describe the dynamics of thin fluidic sheets of soft materials. To use such models in morphogenesis and development r…
Flow Through Porous Media at the Percolation Transition
Mirko Residori, Suvendu Mandal, Axel Voigt +1
We study low-Reynolds-number fluid flow through a two-dimensional porous medium modeled as a Lorentz gas. Using extensive finite element simulations we fully resolve the flow field…
