Instabilities and turbulence in extensile swimmer suspensions
Purnima Jain, Navdeep Rana, Roberto Benzi +1
We study low Reynolds number turbulence in a suspension of polar, extensile, self-propelled inertial swimmers. We review the bend and splay mechanisms that destabilize an ordered f…
Emergent asymmetry in confined bioconvection
Martin A. Bees, Prasad Perlekar
Bioconvection is the prototypical active matter system for hydrodynamic instabilities and pattern formation in suspensions of biased swimming microorganisms, particularly at the di…
Inertia drives concentration-wave turbulence in swimmer suspensions
Purnima Jain, Navdeep Rana, Sriram Ramaswamy +1
We discover an instability mechanism in suspensions of self-propelled particles that does not involve active stress. Instead, it is driven by a subtle interplay of inertia, swimmer…
Defect turbulence in a dense suspension of polar, active swimmers
Navdeep Rana, Rayan Chatterjee, Sunghan Ro +3
We study the effects of inertia in dense suspensions of polar swimmers. The hydrodynamic velocity field and the polar order parameter field describe the dynamics of the suspension.…
Pattern stabilisation in swarms of programmable active matter: a probe for turbulence at large length scales
Pankaj Popli, Prasad Perlekar, Surajit Sengupta
We propose an algorithm for creating stable, ordered, swarms of active robotic agents arranged in any given pattern. The strategy involves suppressing a class of fluctuations known…
