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…
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…
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…
Universal winding properties of chiral active motion
Ion Santra, Urna Basu, Sanjib Sabhapandit
We propose the area swept and the winding angle as the key observables to characterize chiral active motion. We find that the distributions of the scaled area and the…
From Attraction to Repulsion: Emergent Interactions in Harmonically Coupled Active Binary System
Ritwick Sarkar, Sreya Chatterjee, Urna Basu
We investigate the emergent interactions between two active Brownian particles coupled by an attractive harmonic potential and in contact with a thermal reservoir. By analyzing the…
