Non-monotonic diffusion from nonequilibrium driving
Manish Patel, Ritwick Sarkar, Urna Basu +1
The paper presents a unified theoretical framework for particles with reciprocal and nonreciprocal couplings and studies the diffusion of a passive particle driven by an active par…
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…
Stochastic Two-temperature Nonequilibrium Ising model
Debraj Dutta, Ritwick Sarkar, Urna Basu
We investigate the nonequilibrium stationary state (NESS) of the two-dimensional Ising model under a stochastic dichotomous modulation of temperature, which alternates between $T_c…
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…
Ergodicity Breaking in Active Run-and-Tumble Particles in a Double-Well Potential
Urna Basu, Satya N. Majumdar, Alberto Rosso
We investigate the dynamics of a run-and-tumble particle in a double-well potential and demonstrate that, in stark contrast to Brownian particles, active dynamics can lead to stron…
