Role of rotational inertia for collective phenomena in active matter
Lorenzo Caprini, Rahul Kumar Gupta, Hartmut Löwen
We investigate the effect of rotational inertia on the collective phenomena of underdamped active systems and show that the increase of the moment of inertia of each particle favor…
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.…
Phases and excitations of active rod-bead mixtures: simulations and experiments
Harsh Soni, Nitin Kumar, Jyothishraj Nambisan +3
We present a large-scale numerical study, supplemented by experimental observations, of a quasi-two-dimensional active system of polar rods and spherical beads confined between two…
Trapping and sorting active particles: motility-induced condensation & smectic defects
Nitin Kumar, Rahul Kumar Gupta, Harsh Soni +2
We present an experimental realization of the collective trapping phase transition [Kaiser et al., PRL 108, 268307 (2012)], using motile polar granular rods in the presence of a V-…
Sorting motile rods by activity
Nitin Kumar, Harsh Soni, Rahul Kumar Gupta +2
We show, through experiments and simulations, that geometrically polar granular rods, rendered active by the transduction of vertical vibration, undergo a collective trapping phase…
