Biolocomotion and premelting in ice
Jeremy Vachier, J. S. Wettlaufer
Biota are found in glaciers, ice sheets and permafrost. Ice bound micro-organisms evolve in a complex mobile environment facilitated or hindered by a range of bulk and surface inte…
Premelting controlled active matter in ice
Jeremy Vachier, John S. Wettlaufer
Self-propelled particles can undergo complex dynamics due to a range of bulk and surface interactions. When a particle is embedded in a host solid near its bulk melting temperature…
Light controls motility and phase separation of photosynthetic microbes
Alexandros A. Fragkopoulos, Jérémy Vachier, Johannes Frey +4
Large ensembles of interacting, out-of-equilibrium agents are a paradigm of active matter. Their constituents' intrinsic activity may entail the spontaneous separation into localiz…
A fine balance of chemotactic and hydrodynamic torques: when microswimmers orbit a pillar just once
Chenyu Jin, Jérémy Vachier, Soumya Bandyopadhyay +2
We study the detention statistics of self-propelling droplet microswimmers attaching to microfluidic pillars. These droplets show negative autochemotaxis: they shed a persistent re…
Dynamics of sedimenting active Brownian particles
Jérémy Vachier, Marco G. Mazza
We investigate the stochastic dynamics of one sedimenting active Brownian particle in three dimensions under the influence of gravity and passive fluctuations in the translational…
