Synergistic action in colloidal heat engines coupled by non-conservative flows
Sudeesh Krishnamurthy, Rajesh Ganapathy, A. K. Sood
Collective operation of multiple engines to achieve a common objective is a vital step in the design of complex machines. Recent studies have reduced the length scales of engine de…
Emergent Stereoselective Interactions and Self-recognition in Polar Chiral Active Ellipsoids
Pragya Arora, A K Sood, Rajesh Ganapathy
In many active matter systems, particle trajectories have a well-defined handedness or chirality. Whether such chiral activity can introduce stereoselective interactions between pa…
Active nonreciprocal attraction between motile particles in an elastic medium
Rahul Kumar Gupta, Raushan Kant, Harsh Soni +2
We show from experiments and simulations on vibration-activated granular matter that self-propelled polar rods in an elastic medium on a substrate turn and move towards each other.…
Unraveling the Role of Frictional Contacts and Particle Orientational Order During Shear-thickening in Suspensions of Colloidal Rods
Vikram Rathee, Srishti Arora, Daniel L. Blair +3
There is now convincing evidence that inter-particle frictional contacts are essential for observing shear-thickening in concentrated suspensions of compact particles. While this h…
Site-Specific Colloidal Crystal Nucleation by Template-enhanced Particle Transport
Chandan K Mishra, A K Sood, Rajesh Ganapathy
The monomer surface mobility is the single most important parameter that decides the nucleation density and morphology of islands during thin film growth. During template-assisted…
Direct measurements of growing amorphous order and non-monotonic dynamic correlations in a colloidal glass-former
K. Hima Nagamanasa, Shreyas Gokhale, A. K. Sood +1
While the transformation of flowing liquids into rigid glasses is omnipresent, a complete understanding of vitrification remains elusive. Of the numerous approaches aimed at solvin…
