Random resetting in search problems

A Pal, V Stojkoski, T Sandev - Target Search Problems, 2024 - Springer
By repeatedly returning a search process to a known or random state, random resetting
possesses the potential to unveil new trajectories, sidestep potential obstacles, and …

Fractional heterogeneous telegraph processes: Interplay between heterogeneity, memory, and stochastic resetting

T Sandev, A Iomin - Physical Review E, 2024 - APS
Fractional heterogeneous telegraph processes are considered in the framework of
telegrapher's equations accompanied by memory effects. The integral decomposition …

Rate enhancement of gated drift-diffusion process by optimal resetting

A Biswas, A Pal, D Mondal, S Ray - The Journal of Chemical Physics, 2023 - pubs.aip.org
ABSTRACT “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 …

Thermodynamic trade-off relation for first passage time in resetting processes

PS Pal, A Pal, H Park, JS Lee - Physical Review E, 2023 - APS
Resetting is a strategy for boosting the speed of a target-searching process. Since its
introduction over a decade ago, most studies have been carried out under the assumption …

Search with stochastic home returns can expedite classical first passage under resetting

A Biswas, A Kundu, A Pal - Physical Review E, 2024 - APS
Classical first passage under resetting is a paradigm in the search process. Despite its
multitude of applications across interdisciplinary sciences, experimental realizations of such …

Resetting-mediated navigation of an active Brownian searcher in a homogeneous topography

GK Sar, A Ray, D Ghosh, C Hens, A Pal - Soft Matter, 2023 - pubs.rsc.org
Designing navigation strategies for search-time optimization remains of interest in various
interdisciplinary branches in science. Herein, we focus on active Brownian walkers in noisy …

Chiral run-and-tumble walker: Transport and optimizing search

R Mallikarjun, A Pal - Physica A: Statistical Mechanics and its Applications, 2023 - Elsevier
We study the statistical properties of a non-Markovian chiral run-and-tumble particle (CRTP)
in two dimensions in continuous space and time. In our model, the possible orientations of …

Queues with resetting: a perspective

R Roy, A Biswas, A Pal - Journal of Physics: Complexity, 2024 - iopscience.iop.org
Performance modeling is a key issue in queuing theory and operation research. It is well-
known that the length of a queue that awaits service or the time spent by a job in a queue …

Effects of mortality on stochastic search processes with resetting

M Radice - Physical Review E, 2023 - APS
We study the first-passage time to the origin of a mortal Brownian particle, with mortality rate
μ, diffusing in one dimension. The particle starts its motion from x> 0 and it is subject to …

Stochastic resetting prevails over sharp restart for broad target distributions

MR Evans, S Ray - arxiv preprint arxiv:2410.01941, 2024 - arxiv.org
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 …
