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…
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…
Harmonically trapped inertial run-and-tumble particle in one dimension
Debraj Dutta, Anupam Kundu, Sanjib Sabhapandit +1
We study the nonequilibrium stationary state of a one-dimensional inertial run-and-tumble particle (IRTP) trapped in a harmonic potential. We find that the presence of inertia lead…
