A critical assessment of reinforcement learning methods for microswimmer navigation in complex flows
Selim Mecanna, Aurore Loisy, Christophe Eloy
Navigating in a fluid flow while being carried by it, using only information accessible from on-board sensors, is a problem commonly faced by small planktonic organisms. It is also…
Deep reinforcement learning for the olfactory search POMDP: a quantitative benchmark
Aurore Loisy, Robin A. Heinonen
The olfactory search POMDP (partially observable Markov decision process) is a sequential decision-making problem designed to mimic the task faced by insects searching for a source…
The effective diffusivity of ordered and freely evolving bubbly suspensions
Aurore Loisy, Aurore Naso, Peter D. M. Spelt
We investigate the dispersion of a passive scalar such as the concentration of a chemical species, or temperature, in homogeneous bubbly suspensions, by determining an effective di…
Exact results for sheared polar active suspensions with variable liquid crystalline order
Aurore Loisy, Anthony P. Thompson, Jens Eggers +1
We consider a confined sheared active polar liquid crystal with a uniform orientation and study the effect of variations in the magnitude of polarization. Restricting our analysis…
Searching for a source without gradients: how good is infotaxis and how to beat it
Aurore Loisy, Christophe Eloy
Infotaxis is a popular search algorithm designed to track a source of odor in a turbulent environment using information provided by odor detections. To exemplify its capabilities,…
Surfing on turbulence: a strategy for planktonic navigation
Rémi Monthiller, Aurore Loisy, Mimi A. R. Koehl +2
In marine plankton, many swimming species can perceive their environment with flow sensors. Can they use this flow information to travel faster in turbulence? To address this quest…
The nonlinear motion of cells subject to external forces
Aondoyima Ioratim-Uba, Aurore Loisy, Silke Henkes +1
To develop a minimal model for a cell moving in a crowded environment such as in tissue, we investigate the response of a liquid drop of active matter moving on a flat rigid substr…
How many ways a cell can move: the modes of self-propulsion of an active drop
Aurore Loisy, Jens Eggers, Tanniemola B. Liverpool
Numerous physical models have been proposed to explain how cell motility emerges from internal activity, mostly focused on how crawling motion arises from internal processes. Here…
Tractionless Self-Propulsion of Active Drops
Aurore Loisy, Jens Eggers, Tanniemola B. Liverpool
We report on a new mode of self-propulsion exhibited by compact drops of active liquids on a substrate which, remarkably, is tractionless, i.e., which imparts no mechanical stress…
Active suspensions have non-monotonic flow curves and multiple mechanical equilibria
Aurore Loisy, Jens Eggers, Tanniemola B. Liverpool
We point out unconventional mechanical properties of confined active fluids, such as bacterial suspensions, under shear. Using a minimal model of an active liquid crystal with no f…
