Irreversibility and symmetry breaking in the creation and annihilation of defects in active living matter
Avraham Beer, Efraim Dov Neimand, Yuv Agarwal +4
Active living matter continuously creates and annihilates topological defects in a process that remains poorly understood. Here, we investigate these dynamics in two distinct activ…
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…
Topological defects in multi-layered swarming bacteria
Victor Yashunsky, Daniel J. G. Pearce, Gil Ariel +1
Topological defects, which are singular points in a director field, play a major role in shaping active systems. Here, we experimentally study topological defects and the flow patt…
Heat flux balance description of unidirectional freezing and melting dynamics on a translational temperature gradient stage
Michael Chasnitsky, Victor Yashunsky, Ido Braslavsky
Directional solidification occurs in industrial and natural processes, such as freeze-casting, metal processing, biological cryopreservation and freezing of soils. Translational te…
Chiral edge currents in confined fibrosarcoma cells
V. Yashunsky, D. J. G. Pearce, C. Blanch-Mercader +3
During metastatic dissemination, streams of cells collectively migrate through a network of narrow channels within the extracellular matrix, before entering into the blood stream.…
The 2019 Motile Active Matter Roadmap
Gerhard Gompper, Roland G. Winkler, Thomas Speck +34
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…
Particle Ice Front Interaction - The Brownian Ratchet Model
Michael Chasnitsky, Victor Yashunsky, Ido Braslavsky
We treat the problem of particle pushing by growing ice as a free diffusion near a wall that moves with discrete steps. When the particle diffuse away from the surface the surface…
Turbulent dynamics of epithelial cell cultures
C. Blanch-Mercader, V. Yashunsky, S. Garcia +3
In vitro epithelial monolayers exhibit a rich repertoire of collective dynamical behaviours according to microenvironment mechanical features. We investigate the statistical and dy…
Infrared Surface-Plasmon-Resonance -- a novel biophysical tool for studying living cell
M. Golosovsky, V. Lirtsman, V. Yashunsky +2
We discuss the Surface-Plasmon-Resonance (SPR) technique based on Fourier -Transform - InfraRed (FTIR) spectrometry. We explore the potential of the infrared surface plasmon resona…
