Non-monotonic diffusion from nonequilibrium driving
Manish Patel, Ritwick Sarkar, Urna Basu +1
The stochastic dynamics of interacting particles far from equilibrium remains a fundamental challenge in statistical physics. While reciprocal interactions often permit effective o…
Collective Ring Formation in Active Matter
Debraj Dutta, Urna Basu
We study the formation of ring-like structures in interacting active particle systems in two dimensions. The emergent structure shows signatures of both spatial and orientational o…
Universal Features in Atmospheric Particulate Matter Dynamics
Suchismita Banerjee, Koyena Ghosh, Urna Basu +1
We study statistical properties of atmospheric particulate matter fluctuations using six years of daily PM2.5 concentration data from fifty-four Indian cities. Despite diverse urba…
Propulsion dispersion mediated ordering transition in active particles
Debraj Dutta, Urna Basu
We show that dispersion in propulsion strength qualitatively alters collective behavior of active multi-particle systems interacting via short-range attractive potential, giving ri…
