Geometry-induced flocking and topological sound on a defect-free curved surface
Devendra Saini, Atanu Bhatta, Pritha Dolai
We study an ordered polar active flock on a torus and show that topological sound persists on a compact curved surface without topological defects or physical boundaries. Using the…
Shape Evolution and Dynamics of Deformable Ring
Arun Kumar, Partha Sarathi Mondal, Pritha Dolai +1
We numerically investigate the dynamics of a deformable closed ring filled with active particles. The ring is modeled as a flexible boundary made up of passive beads interacting wi…
Inducing a bound state between active particles
Pritha Dolai, Simon Krekels, Christian Maes
We show that two active particles can form a bound state by coupling to a driven nonequilibrium environment. We specifically investigate the case of two mutually noninteracting run…
Harnessing confinement and driving to tune active particle dynamics
Aniruddh Murali, Pritha Dolai, Ashwini Krishna +2
A distinguishing feature of active particles is the nature of the non-equilibrium noise driving their dynamics. Control of these noise properties is, therefore, of both fundamental…
Phase separation in binary mixtures of active and passive particles
Pritha Dolai, Aditi Simha, Shradha Mishra
We study binary mixtures of small active and big passive athermal particles interacting via soft repulsive forces on a frictional substrate. Athermal self propelled particles are k…
Universal spatio-temporal scaling of distortions in a drifting lattice
Pritha Dolai, Abhik Basu, Aditi Simha
We study the dynamical response to small distortions of a lattice about its uniform state, drifting through a dissipative medium due to an external force, and show, analytically an…
