Coarsening of topological defects in 2D polar active matter
Soumyadeep Mondal, Pankaj Popli, Sumantra Sarkar
We numerically study the coarsening of topological defects in 2D polar active matter and make several interesting observations and predictions. (i) The long time state is character…
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…
Exploring the link between crystal defects and non-affine displacement fluctuations
Pankaj Popli, Sayantani Kayal, Peter Sollich +1
We generalize, and then use, a recently introduced formalism to study thermal fluctuations of atomic displacements in several two and three dimensional crystals. We study both clos…
Translationally invariant colloidal crystal templates
Pankaj Popli, Saswati Ganguly, Surajit Sengupta
We show that dynamic, feed-back controlled optical traps, whose positions depend on the instantaneous local configuration of particles in a pre-determined way, can stabilise colloi…
