P Singh, A Pal - Journal of Physics A: Mathematical and …, 2022 - iopscience.iop.org
We study the statistical properties of first-passage time functionals of a one dimensional
Brownian motion in the presence of stochastic resetting. A first-passage functional is defined …

First-passage functionals of Brownian motion in logarithmic potentials and heterogeneous diffusion

M Radice - Physical Review E, 2023 - APS
We study the statistics of random functionals Z=∫ 0 T [x (t)] γ− 2 dt, where x (t) is the
trajectory of a one-dimensional Brownian motion with diffusion constant D under the effect of …

Controlling Uncertainty of Empirical First-Passage Times in the Small-Sample Regime

R Bebon, A Godec - Physical Review Letters, 2023 - APS
We derive general bounds on the probability that the empirical first-passage time τ n≡∑ i=
1 n τ i/n of a reversible ergodic Markov process inferred from a sample of n independent …

Exact calculation of the mean first-passage time of continuous-time random walks by nonhomogeneous Wiener–Hopf integral equations

M Dahlenburg, G Pagnini - Journal of Physics A: Mathematical …, 2022 - iopscience.iop.org
We study the mean first-passage time (MFPT) for asymmetric continuous-time random walks
in continuous-space characterised by waiting-times with finite mean and by jump-sizes with …

First-passage functionals for Ornstein–Uhlenbeck process with stochastic resetting

A Dubey, A Pal - Journal of Physics A: Mathematical and …, 2023 - iopscience.iop.org
We study the statistical properties of first-passage Brownian functionals (FPBFs) of an
Ornstein–Uhlenbeck process in the presence of stochastic resetting. We consider a one …

Discrete sampling of extreme events modifies their statistics

L Zarfaty, E Barkai, DA Kessler - Physical Review Letters, 2022 - APS
Extreme value (EV) statistics of correlated systems are widely investigated in many fields,
spanning the spectrum from weather forecasting to earthquake prediction. Does the …

The first-passage area of Ornstein-Uhlenbeck process revisited

M Abundo - Stochastic Analysis and Applications, 2023 - Taylor & Francis
Abstract For Ornstein-Uhlenbeck process X (t), starting from X (0)= x> 0, we highlight some
results about the first-passage time of X (t) through zero and its first-passage area, that is the …

Work statistics at first-passage times

IN Mamede, P Singh, A Pal, CE Fiore… - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate the work fluctuations in an overdamped non-equilibrium process that is
stopped at a stochastic time. The latter is characterized by a first passage event that marks …

Extremal statistics for first-passage trajectories of drifted Brownian motion under stochastic resetting

W Guo, H Yan, H Chen - Journal of Statistical Mechanics: Theory …, 2024 - iopscience.iop.org
We study the extreme value statistics of first-passage trajectories generated from a one-
dimensional drifted Brownian motion subject to stochastic resetting to the starting point with …

Mean first-passage time of a random walker under Galilean transformation

M Dahlenburg, G Pagnini - arXiv preprint arXiv:2306.07828, 2023 - arxiv.org
We consider a continuous-time random walk model with finite-mean waiting-times and we
study the mean first-passage time (MFPT) as estimated by an observer in a reference frame …
