Stochastic resetting prevails over sharp restart for broad target distributions
Martin R. Evans, Somrita Ray
Resetting has been shown to reduce the completion time for a stochastic process, such as the first passage time for a diffusive searcher to find a target. The time between two cons…
Rate enhancement of gated drift-diffusion process by optimal resetting
Arup Biswas, Arnab Pal, Debasish Mondal +1
`Gating' is a widely observed phenomenon in biochemistry that describes the transition between the activated (or open) and deactivated (or closed) states of an ion-channel, which m…
Expediting Feller process with stochastic resetting
Somrita Ray
We explore the effect of stochastic resetting on the first-passage properties of Feller process. The Feller process can be envisioned as space-dependent diffusion, with diffusion c…
Resetting transition is governed by an interplay between thermal and potential energy
Somrita Ray, Shlomi Reuveni
A dynamical process that takes a random time to complete, e.g., a chemical reaction, may either be accelerated or hindered due to resetting. Tuning system parameters such as temper…
Space-dependent diffusion with stochastic resetting: A first-passage study
Somrita Ray
We explore the effect of stochastic resetting on the first-passage properties of space-dependent diffusion in presence of a constant bias. In our analytically tractable model syste…
Diffusion with resetting in a logarithmic potential
Somrita Ray, Shlomi Reuveni
We study the effect of resetting on diffusion in a logarithmic potential. In this model, a particle diffusing in a potential is reset, i.e., taken back to its i…
Péclet number governs transition to acceleratory restart in drift-diffusion
Somrita Ray, Debasish Mondal, Shlomi Reuveni
First-passage processes can be divided in two classes: those that are accelerated by the introduction of restart and those that display an opposite response. In physical systems, a…
Stochastic thermodynamics of periodically driven systems: Fluctuation theorem for currents and unification of two classes
Somrita Ray, Andre C. Barato
Periodic driving is used to operate machines that go from standard macroscopic engines to small non-equilibrium micro-sized systems. Two classes of such systems are small heat engi…
Dispersion of the time spent in a state: General expression for unicyclic model and dissipation-less precision
Somrita Ray, Andre C. Barato
We compare the relation between dispersion and dissipation for two random variables that can be used to characterize the precision of a Brownian clock. The first random variable is…
