Emergent short-range repulsion for attractively coupled active particles
Ritwick Sarkar, Urna Basu
We show that heterogeneity in self-propulsion speed can lead to the emergence of a robust effective short-range repulsion among active particles interacting via long-range attracti…
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…
Universal Dynamics of a Passive Particle Driven by Brownian Motion
Urna Basu, P. L. Krapivsky, Satya N. Majumdar
We investigate the overdamped dynamics of a `passive' particle driven by nonreciprocal interaction with a `driver' Brownian particle. When the interaction between them is short-ran…
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…
Harmonic chain driven by active Rubin bath: transport properties and steady-state correlations
Ritwick Sarkar, Ion Santra, Urna Basu
Characterizing the properties of an extended system driven by active reservoirs is a question of increasing importance. Here we address this question in two steps. We start by inve…
Tagged particle behavior in a harmonic chain of direction reversing active Brownian particles
Shashank Prakash, Urna Basu, Sanjib Sabhapandit
We study the tagged particle dynamics in a harmonic chain of direction reversing active Brownian particles, with spring constant , rotation diffusion coefficient ,…
