Jerky chiral active particles
Stephy Jose, Hartmut Löwen
We introduce jerky chiral active Brownian particles (jcABPs), a generalization of conventional chiral active Brownian particles (cABPs) subjected to jerk, the time derivative of ac…
Diffusive noise controls early stages of genetic demixing
Rashmiranjan Bhutia, Stephy Jose, Prasad Perlekar +1
Theoretical descriptions of the stepping-stone model, a cornerstone of spatial population genetics, have long overlooked diffusive noise arising from migration dynamics. We derive…
Current fluctuations in finite-sized one-dimensional non-interacting passive and active systems
Arup Biswas, Stephy Jose, Arnab Pal +1
We investigate the problem of effusion of particles initially confined in a finite one-dimensional box of size . We study both passive as well active scenarios, involving non-in…
Effect of initial conditions on current fluctuations in non-interacting active particles
Stephy Jose, Alberto Rosso, Kabir Ramola
We investigate the effect of initial conditions on the fluctuations of the integrated density current across the origin () up to a given time in a one-dimensional system o…
Generalized disorder averages and current fluctuations in run and tumble particles
Stephy Jose, Alberto Rosso, Kabir Ramola
We present exact results for the fluctuations in the number of particles crossing the origin up to time in a collection of non-interacting run and tumble particles in one dimen…
Current fluctuations in an interacting active lattice gas
Stephy Jose, Rahul Dandekar, Kabir Ramola
We study the fluctuations of the integrated density current across the origin up to time in a lattice model of active particles with hard-core interactions. This model is amena…
First passage statistics of active random walks on one and two dimensional lattices
Stephy Jose
We investigate the first passage statistics of active continuous time random walks with Poissonian waiting time distribution on a one dimensional infinite lattice and a two dimensi…
Active Random Walks in One and Two Dimensions
Stephy Jose, Dipanjan Mandal, Mustansir Barma +1
We investigate active lattice walks: biased continuous time random walks which perform orientational diffusion between lattice directions in one and two spatial dimensions. We stud…
First passage statistics of Poisson random walks on lattices
Stephy Jose
The first passage statistics of a continuous time random walker with Poisson distributed jumps on one and two dimensional infinite lattices is investigated. An exact expression for…
