Tuning the performance of a micrometer-sized Stirling engine through reservoir engineering
Niloyendu Roy, Nathan Leroux, A K Sood +1
Colloidal heat engines are paradigmatic models to understand the conversion of heat into work in a noisy environment - a domain where biological and synthetic nano/micro machines f…
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.…
Imaging the coherent propagation of collective modes in the excitonic insulator candidate TaNiSe at room temperature
Hope M. Bretscher, Paolo Andrich, Yuta Murakami +10
Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insu…
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…
