Universal winding properties of chiral active motion
Ion Santra, Urna Basu, Sanjib Sabhapandit
We propose the area swept and the winding angle as the key observables to characterize chiral active motion. We find that the distributions of the scaled area and th…
Brownian motion with stochastic energy renewals
Ion Santra, Kristian Stølevik Olsen
We investigate the impact of intermittent energy injections on a Brownian particle, modeled as stochastic renewals of its kinetic energy to a fixed value. Between renewals, the par…
Dynamics of switching processes: general results and applications to intermittent active motion
Ion Santra, Kristian Stølevik Olsen, Deepak Gupta
Systems switching between different dynamical phases is an ubiquitous phenomenon. The general understanding of such a process is limited. To this end, we present a general expressi…
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…
