Flocking under Fast and Large Jumps: Stability, Chaos, and Traveling Waves

Sayan Banerjee, Amarjit Budhiraja, Dilshad Imon

The paper analyzes a flocking model where particles make fast, large random jumps with rates depending on their distance from the center of mass, establishing fluid limits, propaga…

Bi-infinite systems of singularly interacting Brownian particles and the KPZ equation

Sayan Banerjee, Amarjit Budhiraja, Peter Rudzis

We study a bi-infinite system of interacting Brownian particles on the real line with singular asymmetric interactions mediated by the collision local times. Particles perform Brow…

Long Time Asymptotics for the Stochastic Follow-the-Leader System

Sayan Banerjee, Amarjit Budhiraja, Dilshad Imon

We introduce and analyze a class of interacting particle systems on the real line that combine features of the stochastic rat race and (deterministic) follow-the-leader models. The…

Fluctuations of the Atlas model from inhomogeneous stationary profiles

Sayan Banerjee, Amarjit Budhiraja, Peter Rudzis

The infinite Atlas model describes the evolution of a countable collection of Brownian particles on the real line, where the lowest particle is given a drift of .…

Strong existence, pathwise uniqueness and chains of collisions in infinite Brownian particle systems

Sayan Banerjee, Amarjit Budhiraja, Peter Rudzis

We study strong existence and pathwise uniqueness for a class of infinite-dimensional singular stochastic differential equations (SDE), with state space as the cone $\{x \in \mathb…
