Optimizing collective behavior of communicating active particles with machine learning

open access: yesMachine Learning: Science and Technology
Bacteria and other self-propelling microorganisms produce and respond to signaling molecules to communicate with each other (quorum sensing) and to direct their collective behavior.

Stochastic thermodynamics for active matter

open access: yes, 2016
The theoretical understanding of active matter, which is driven out of equilibrium by directed motion, is still fragmental and model oriented. Stochastic thermodynamics, on the other hand, is a comprehensive theoretical framework for driven systems that ...

Carbonate Micromotors for Treatment of Construction Effluents

open access: yesNanomaterials, 2020
Concrete in construction has recently gained media coverage for its negative CO2 footprint, but this is not the only problem associated with its use. Due to its chemical composition, freshly poured concrete changes the pH of water coming in contact with ...

Mechanical pressure and momentum conservation in dry active matter

open access: yes, 2017
We relate the breakdown of equations of states for the mechanical pressure of generic dry active systems to the lack of momentum conservation in such systems. We show how sources and sinks of momentum arise generically close to confining walls.

Dynamics of self-propelled particles passing a bottleneck

open access: yesNew Journal of Physics, 2020
We study the passage of active and passive granular particles through a bottleneck under gravitational bias. The grains are pharmaceutical capsules with spherocylindrical shapes on a vibrating table. The vibrating ground plate is slightly tilted in order

Linking neutrino oscillations to the nucleosynthesis of elements

open access: yes, 2015
Neutrino interactions with matter play an important role in determining the nucleosynthesis outcome in explosive astrophysical environments such as core-collapse supernovae or mergers of compact objects.

Phase separation and large deviations of lattice active matter

open access: yes, 2017
Off-lattice active Brownian particles form clusters and undergo phase separation even in the absence of attractions or velocity-alignment mechanisms. Arguments that explain this phenomenon appeal only to the ability of particles to move persistently in a

Defect order in active nematics on a curved surface

open access: yesNew Journal of Physics, 2020
We investigate the effects of extrinsic curvature on the turbulent behavior of a 2D active nematic confined to the surface of a cylinder. The surface of a cylinder has no intrinsic curvature and only extrinsic curvature.

Destabilization of a flow focused suspension of magnetotactic bacteria

open access: yes, 2016
Active matter is a new class of material, intrinsically out-of equilibrium with intriguing properties. So far, the recent upsurge of studies has mostly focused on the spontaneous behavior of these systems --in the absence of external constraints or ...
