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…
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…
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…
