Crystal to liquid cross-over for active particles with inverse-square power-law interaction
Saikat Santra, Leo Touzo, Chandan Dasgupta +6
We consider a one-dimensional system comprising of run-and-tumble particles confined in a harmonic trap interacting via a repulsive inverse-square power-law interaction. We num…

Crossover in densities of confined particles with finite range of interaction
Saikat Santra, Anupam Kundu
We study a one-dimensional classical system of particles confined within a harmonic trap. Interactions among these particles are dictated by a pairwise potential , where…

Tracer dynamics in the active random average process
Saikat Santra, Prashant Singh, Anupam Kundu
We investigate the dynamics of tracer particles in the random average process (RAP), a single-file system in one dimension. In addition to the position, every particle possesses an…
