Stability of interlocked self-propelled dumbbell clusters
Fabian Jan Schwarzendahl, Abraham Maulean-Amieva, C. Patrick Royall +1
Combining experimental observations of Quincke roller clusters with computer simulations and a stability analysis, we explore the formation and stability of two interlocked self-pr…
Collective mechano-response dynamically tunes cell-size distributions in growing bacterial colonies
René Wittmann, G. H. Philipp Nguyen, Hartmut Löwen +2
Mechanical stresses stemming from environmental factors are a key determinant of cellular behavior and physiology. Yet, the role of self-induced biomechanical stresses in growing b…
Active particles using reinforcement learning to navigate in complex motility landscapes
Paul A. Monderkamp, Fabian Jan Schwarzendahl, Michael A. Klatt +1
As the length scales of the smallest technology continue to advance beyond the micron scale it becomes increasingly important to equip robotic components with the means for intelli…
Active Colloids in Harmonic Optical Potentials
Ivo Buttinoni, Lorenzo Caprini, Laura Alvarez +2
We study the motion of active patchy colloids in an optical trap using experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype mi…
A one-dimensional three-state run-and-tumble model with a `cell cycle'
Davide Breoni, Fabian Jan Schwarzendahl, Ralf Blossey +1
We study a one-dimensional three-state run-and-tumble model motivated by the bacterium Caulobacter crescentus which displays a cell cycle between two non-proliferation mobile phase…
Do active nematic self-mixing dynamics help growing bacterial colonies to maintain local genetic diversity?
Fabian Jan Schwarzendahl, Daniel A. Beller
Recent studies have shown that packings of cells, both eukaryotic cellular tissues and growing or swarming bacterial colonies, can often be understood as active nematic fluids. A k…
Mutation induced infection waves in diseases like COVID-19
Fabian Jan Schwarzendahl, Jens Grauer, Benno Liebchen +1
After more than 6 million deaths worldwide, the ongoing vaccination to conquer the COVID-19 disease is now competing with the emergence of increasingly contagious mutations, repeat…
