Mechanically concealed holes
Kanka Ghosh, Andreas M. Menzel
When a hole is introduced into an elastic material, it will usually act to reduce the overall mechanical stiffness. A general ambition is to investigate whether a stiff shell aroun…
Magnetically Driven Elastic Microswimmers: Exploiting Hysteretic Collapse for Autonomous Propulsion and Independent Control
Theo Lequy, Andreas M. Menzel
When swimming at low Reynolds numbers, inertial effects are negligible and reciprocal movements cannot induce net motion. Instead, symmetry breaking is necessary to achieve net pro…
Hydrodynamic flows induced by localized torques (rotlets) in wedge-shaped geometries
Abdallah Daddi-Moussa-Ider, Jakob Mihatsch, Michael J. Mitchell +2
Wedge-shaped geometries in low-Reynolds-number flows are of increasing importance, for instance, in the design of microfluidic devices. The corresponding Green's functions describi…
Diffusion through complex confining environments: fluctuating triply periodic minimal surfaces
Jakob Mihatsch, Andreas M. Menzel
The transport of individual entities through interconnected structures is a process of practical relevance both in biology and technology. Examples are given by diffusive dynamics…
Phasebook: A Survey of Selected Open Problems in Phase Retrieval
Marc Allain, Selin Aslan, Wim Coene +13
Phase retrieval is an inverse problem that, on one hand, is crucial in many applications across imaging and physics, and, on the other hand, leads to deep research questions in the…
Linear theory of viscoelasticity in a generalized hydrodynamic framework
Andreas M. Menzel
A generalized hydrodynamic theory that systematically incorporates elasticity and viscoelasticity had been derived about a quarter of a century ago. It is based on a strictly Euler…
