Random motion of a circle microswimmer in a random environment
Oleksandr Chepizhko, Thomas Franosch
We simulate the dynamics of a single circle microswimmer exploring a disordered array of fixed obstacles. The interplay of two different types of randomness, quenched disorder and…
Chromatin and cytoskeletal tethering determine nuclear morphology in progerin expressing cells
M. C. Lionetti, S. Bonfanti, M. R. Fumagalli +6
The nuclear morphology of eukaryotic cells is determined by the interplay between the lamina forming the nuclear skeleton, the chromatin inside the nucleus and the coupling with th…
Ideal circle microswimmers in crowded media
Oleksandr Chepizhko, Thomas Franosch
Microswimmers are exposed in nature to crowded environments and their transport properties depend in a subtle way on the interaction with obstacles. Here, we investigate a model fo…
Unjamming of active rotators
Linda Ravazzano, Maria Chiara Lionetti, Maria Rita Fumagalli +5
Active particle assemblies can exhibit a wide range of interesting dynamical phases depending on internal parameters such as density, adhesion strength or self-propulsion. Active s…
From jamming to collective cell migration through a boundary induced transition
Oleksandr Chepizhko, Maria Chiara Lionetti, Chiara Malinverno +3
Cell monolayers provide an interesting example of active matter, exhibiting a phase transition from a flowing to jammed state as they age. Here we report experiments and numerical…
Universal statistics of epithelial tissue topology
Abdulaziz Abdullah, Demetris Avraam, Oleksandr Chepizhko +4
Cells forming various epithelial tissues have a strikingly universal distribution for the number of their edges. It is generally assumed that this topological feature is predefined…
