Motility-induced clustering of active particles under soft confinement
Timo Knippenberg, Ashreya Jayaram, Thomas Speck +1
We investigate the structural and dynamic properties of active Brownian particles (APs) confined within a soft annulus-shaped channel. Depending on the strength of the confinement…
Collective Hall current in chiral active fluids: Coupling of phase and mass transport through traveling bands
Frank Siebers, Robin Bebon, Ashreya Jayaram +1
Active fluids composed of constituents that are constantly driven away from thermal equilibrium can support spontaneous currents and can be engineered to have unconventional transp…
Effective dynamics and fluctuations of a trapped probe moving in a fluid of active hard discs
Ashreya Jayaram, Thomas Speck
We study the dynamics of a single trapped probe surrounded by self-propelled active particles in two dimensions. In the limit of large size separation, we perform an adiabatic elim…
Force generation in confined active fluids: The role of microstructure
Shuvojit Paul, Ashreya Jayaram, N Narinder +2
We experimentally determine the force exerted by a bath of active particles onto a passive probe as a function of its distance to a wall and compare it to the measured averaged den…
Hunting active Brownian particles: Learning optimal behavior
Marcel Gerhard, Ashreya Jayaram, Andreas Fischer +1
We numerically study active Brownian particles that can respond to environmental cues through a small set of actions (switching their motility and turning left or right with respec…
Vorticity Determines the Force on Bodies Immersed in Active Fluids
Thomas Speck, Ashreya Jayaram
When immersed into a fluid of active Brownian particles, passive bodies might start to undergo linear or angular directed motion depending on their shape. Here we exploit the diver…
From scalar to polar active matter: Connecting simulations with mean-field theory
Ashreya Jayaram, Andreas Fischer, Thomas Speck
We study numerically the phase behavior of self-propelled elliptical particles interacting through the "hard" repulsive Gay-Berne potential at infinite Péclet number. Changing a si…
