We study experimentally and theoretically the optimal mean time needed by a free diffusing Brownian particle to reach a target at a distance L from an initial position in the presence of resetting. Both the initial position and the resetting position are Gaussian distributed with width $\sigma$. We derived and tested two resetting protocols, one with a periodic and one with random (Poissonian) resetting times. We computed and measured the full first-passage probability distribution that… Expand

Resetting with stochastic return through linear confining potential
We consider motion of an overdamped Brownian particle subject to stochastic resetting in one dimension. In contrast to the usual setting where the particle is instantaneously reset to a preferredExpand
Non-linear diffusion with stochastic resetting
Resetting or restart, when applied to a stochastic process, usually brings its dynamics to a timeindependent stationary state. In turn, the optimal resetting rate makes the mean time to reach aExpand
First passage under restart for discrete space and time: Application to one-dimensional confined lattice random walks.
This paper studies discrete space and time first-passage processes under discrete time resetting in a general setup without specifying their forms to understand the effect of restart on the spatiotemporal dynamics of confined lattice random walks in arbitrary dimensions. Expand
Stochastic resetting in the Kramers problem: A Monte Carlo approach
The theory of stochastic resetting asserts that restarting a search process at certain times may accelerate the finding of a target. In the case of a classical diffusing particle trapped in aExpand
Time-averaging and emerging nonergodicity upon resetting of fractional Brownian motion and heterogeneous diffusion processes
It is found that the resetting dynamics of originally ergodic FBM for superdiffusive choices of the Hurst exponent develops distinct disparities in the scaling behavior and magnitudes of the MSDs and mean TAMSDs, indicating so-called weak ergodicity breaking (WEB). Expand
The inspection paradox in stochastic resetting
The remaining travel time of a plane shortens with every minute that passes from its departure, and a flame diminishes a candle with every second it burns. Such everyday occurrences bias us to thinkExpand
Resetting transition is governed by an interplay between thermal and potential energy.
This work proposes a general framework that reveals that the resetting transition is governed by an interplay between the thermal and potential energy, and is illustrated for different classes of potentials that are used to model a wide variety of stochastic processes with numerous applications.

Stochastic resetting of active Brownian particles with Lorentz force.
It is shown that whereas for a uniform magnetic field the properties of the stationary state of the active system can be obtained from its passive counterpart, novel features emerge in the case of an inhomogeneous magnetic field which have no counterpart in passive systems. Expand
Inducing and optimizing Markovian Mpemba effect with stochastic reset
A hot Markovian system can cool down faster than a colder one: this is known as the Mpemba effect. Here, we show that a non-equilibrium driving via stochastic reset can induce this phenomenon, whenExpand


Diffusion under time-dependent resetting
We study a Brownian particle diffusing under a time-modulated stochastic resetting mechanism to a fixed position. The rate of resetting r(t) is a function of the time t since the last reset event. WeExpand
Diffusion with optimal resetting
We consider the mean time to absorption by an absorbing target of a diffusive particle with the addition of a process whereby the particle is reset to its initial position with rate r. We considerExpand
Run and tumble particle under resetting: a renewal approach
This work considers a particle undergoing run and tumble dynamics, in which its velocity stochastically reverses, in one dimension and shows that the the mean time to absorption is always less for velocity randomization than for position-only resetting. Expand
Diffusion with resetting in arbitrary spatial dimension
We consider diffusion in arbitrary spatial dimension d with the addition of a resetting process wherein the diffusive particle stochastically resets to a fixed position at a constant rate $r$. WeExpand
Transport properties and first-arrival statistics of random motion with stochastic reset times.

First Order Transition for the Optimal Search Time of Lévy Flights with Resetting.
An intermittent search process in one dimension where a searcher undergoes a discrete time jump process starting at x_{0}≥0 and the mean first passage time (MFPT) to the origin is studied, which has a global minimum in the (μ,r) plane. Expand
Work Fluctuations and Jarzynski Equality in Stochastic Resetting.
It is shown that the distribution function of the work typically, in asymptotic times, converges to a universal Gaussian form for any protocol as long as that is also renewed after each resetting event. Expand
Optimal first-arrival times in Lévy flights with resetting.
A formula for the mean first arrival time (MFAT) to a predefined target position reached by a meandering particle is derived and the efficiency of the proposed searching strategy is analyzed by investigating criteria for an optimal MFAT. Expand

A comprehensive study of the first-passage properties of the Brownian particle diffusing in a one-dimensional interval with absorbing end points and shows how this set-up is a manifestation of a success-failure problem. Expand
Time-dependent density of diffusion with stochastic resetting is invariant to return speed.
A situation where upon resetting the diffusing particle returns to the origin at a finite (rather than infinite) speed is considered, and the time-dependent distribution describing the particle's position in this model is completely invariant to the speed of return. Expand
