Stochastic resetting of a population of random walks with resetting-rate-dependent diffusivity

نویسندگان

چکیده

We consider the problem of diffusion with stochastic resetting in a population random walks where coefficient is not constant, but behaves as power-law average rate population. Resetting occurs only beyond threshold distance from origin. This motivated by physical realizations like soft matter under shear, walk induced events other walks. first reformulate broader context so-called H\'ebraud-Lequeux model for plasticity dense matter, which diffusivity proportional to rate. Depending on parameter values, response weak external field may be either linear or non-linear non-zero position vanishing applied field, and transition between these two regimes interpreted continuous phase transition. Extending considering general relation rate, we notably find discontinuous finite small limit.

Characterization of stationary states in random walks with stochastic resetting.

It is known that introducing a stochastic resetting in a random-walk process can lead to the emergence of a stationary state. Here we study this point from a general perspective through the derivation and analysis of mesoscopic (continuous-time random walk) equations for both jump and velocity models with stochastic resetting. In the case of jump models it is shown that stationary states emerge...

Diffusion with stochastic resetting.

We study simple diffusion where a particle stochastically resets to its initial position at a constant rate r. A finite resetting rate leads to a nonequilibrium stationary state with non-Gaussian fluctuations for the particle position. We also show that the mean time to find a stationary target by a diffusive searcher is finite and has a minimum value at an optimal resetting rate r*. Resetting ...

Network reconstruction from random phase resetting.

We propose a novel method of reconstructing the topology and interaction functions for a general oscillator network. An ensemble of initial phases and the corresponding instantaneous frequencies is constructed by repeating random phase resets of the system dynamics. The desired details of network structure are then revealed by appropriately averaging over the ensemble. The method is applicable ...

Convergence rate of moments in stochastic approximation with simultaneous perturbation gradient approximation and resetting

The sequence of recursive estimators for function minimization generated by Spall’s simultaneous perturbation stochastic approximation (SPSA) method, presented in [25], combined with a suitable restarting mechanism is considered. It is proved that this sequence converges under certain conditions with rate O(n ) for some >0, the best value being = 2=3, where the rate is measured by the Lq-norm o...

Diffusivity of a random walk on random walks

We consider a random walk ( Z (1) n , · · · , Z n ) ∈ Z with the constraint that each coordinate of the walk is at distance one from the following one. In this paper, we show that this random walk is slowed down by a variance factor σ K = 2 K+2 with respect to the case of the classical simple random walk without constraint.
