Chirality across scales in tissue dynamics
Sihan Chen, Doruk Efe Gökmen, Michel Fruchart +4
Chiral processes that lack mirror symmetry pervade nature from enantioselective molecular interactions to the asymmetric development of organisms. An outstanding challenge at the i…
Statistical physics of active matter, cell division and cell aggregation
Jean-François Joanny, Joseph O. Indekeu
In these Lecture Notes we aim at clarifying how soft matter physics, and herein notably statistical mechanics and fluid mechanics, can be engaged to understand and manipulate non-e…
The importance of being discrete -- An agent-based model for active nematics and more
Mathieu Dedenon, Carles Blanch-Mercader, Karsten Kruse +1
We propose an agent-based model of active flexible rods. Inspired by cytoskeletal flows, we introduce activity by an internal flow that contributes to the dissipative forces. The a…
Dynamical arrest in active nematic turbulence
Ido Lavi, Ricard Alert, Jean-François Joanny +1
Active fluids display spontaneous turbulent-like flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material proper…
Spontaneous flows in active smectics with dislocations
Shao-Zhen Lin, Frank Jülicher, Jacques Prost +1
We construct a hydrodynamic theory of active smectics A in two-dimensional space, including the creation/annihilation and motility of dislocations with Burgers' number . We d…
Environment-stored memory in active nematics and extra-cellular matrix remodeling
Ram M. Adar, Jean-François Joanny
Many active systems display nematic order, while interacting with their environment. In this work, we show theoretically how environment-stored memory acts an effective external fi…
