Long time behavior of run-and-tumble particles in two dimensions
Ion Santra, Urna Basu, Sanjib Sabhapandit
We study the long-time asymptotic behavior of the position distribution of a run-and-tumble particle (RTP) in two dimensions and show that the distribution at a time can be exp…
Stationary states of activity-driven harmonic chains
Ritwick Sarkar, Ion Santra, Urna Basu
We study the stationary state of a chain of harmonic oscillators driven by two active reservoirs at the two ends. These reservoirs exert correlated stochastic forces on the boundar…
Dynamical fluctuations of a tracer coupled to active and passive particles
Ion Santra
We study the induced dynamics of an inertial tracer particle elastically coupled to passive or active Brownian particles. We integrate out the environment degrees of freedom to obt…
Effect of stochastic resetting on Brownian motion with stochastic diffusion coefficient
Ion Santra, Urna Basu, Sanjib Sabhapandit
We study the dynamics of a Brownian motion with a diffusion coefficient which evolves stochastically. We first study this process in arbitrary dimensions and find the scaling form…
Effect of tax dynamics on linearly growing processes under stochastic resetting: a possible economic model
Ion Santra
We study a system of agents, whose wealth grows linearly, under the effect of stochastic resetting and interacting via a tax-like dynamics -- all agents donate a part of their…
Universal framework for the long-time position distribution of free active particles
Ion Santra, Urna Basu, Sanjib Sabhapandit
Active particles self-propel themselves with a stochastically evolving velocity, generating a persistent motion leading to a non-diffusive behavior of the position distribution. Ne…
