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…

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…

Inertial Dynamics of Run-and-Tumble Particle
Debraj Dutta, Anupam Kundu, Urna Basu
We study the dynamics of a single inertial run-and-tumble particle on a straight line. The motion of this particle is characterized by two intrinsic time-scales, namely, an inertia…
