First-passage statistics of random walks: a general approach via Riemann-Hilbert problems
Mattia Radice, Giampaolo Cristadoro
We study first-passage statistics for one-dimensional random walks with independent and identically distributed jumps starting from the origin. We focus on the joint distribu…
Optimal conditions for first passage of jump processes with resetting
Mattia Radice, Giampaolo Cristadoro, Samudrajit Thapa
We investigate the first passage time beyond a barrier located at of a random walk with independent and identically distributed jumps, starting from . The walk is s…
Optimizing Leapover Lengths of Lévy Flights with Resetting
Mattia Radice, Giampaolo Cristadoro
We consider a one-dimensional search process under stochastic resetting conditions. A target is located at and a searcher, starting from the origin, performs a discrete-ti…
First-passage functionals of Brownian motion in logarithmic potentials and heterogeneous diffusion
Mattia Radice
We study the statistics of random functionals , where is the trajectory of a one-dimensional Brownian motion with diffusion…
Effects of mortality on stochastic search processes with resetting
Mattia Radice
We study the first-passage time to the origin of a mortal Brownian particle, with mortality rate , diffusing in one dimension. The particle starts its motion from and i…
Non-homogeneous random walks with stochastic resetting: an application to the Gillis model
Mattia Radice
We consider the problem of the first passage time to the origin of a spatially non-homogeneous random walk with a position-dependent drift, known as the Gillis random walk, in the…
Extreme value statistics of positive recurrent centrally biased random walks
Roberto Artuso, Manuele Onofri, Gaia Pozzoli +1
We consider the extreme value statistics of centrally-biased random walks with asymptotically-zero drift in the ergodic regime. We fully characterize the asymptotic distribution of…
Diffusion processes with Gamma-distributed resetting and non-instantaneous returns
Mattia Radice
We consider the dynamical evolution of a Brownian particle undergoing stochastic resetting, meaning that after random periods of time it is forced to return to the starting positio…
The one-dimensional telegraphic process with noninstantaneous stochastic resetting
Mattia Radice
In this paper we consider the one-dimensional dynamical evolution of a particle traveling at constant speed and performing, at a given rate, random reversals of the velocity direct…
A continuous-time random walk extension of the Gillis model
Gaia Pozzoli, Mattia Radice, Manuele Onofri +1
We consider a continuous-time random walk which is the generalization, by means of the introduction of waiting periods on sites, of the one-dimensional nonhomogeneous random walk w…
Exploring the Gillis model: a discrete approach to diffusion in logarithmic potentials
Manuele Onofri, Gaia Pozzoli, Mattia Radice +1
Gillis model, introduced more than 60 years ago, is a non-homogeneous random walk with a position dependent drift. Though parsimoniously cited both in the physical and mathematical…
Statistics of occupation time and connection to local properties of non-homogeneous random walks
Mattia Radice, Manuele Onofri, Roberto Artuso +1
We consider the statistics of occupation times, the number of visits at the origin and the survival probability for a wide class of stochastic processes, which can be classified as…
Transport properties and ageing for the averaged Lévy-Lorentz gas
Mattia Radice, Manuele Onofri, Roberto Artuso +1
We consider a persistent random walk on an inhomogeneous environment where the reflection probability depends only on the distance from the origin. Such an environment is the resul…
Non-homogeneous persistent random walks and averaged environment for the Lévy-Lorentz gas
Roberto Artuso, Giampaolo Cristadoro, Manuele Onofri +1
We consider transport properties for a non-homogeneous persistent random walk, that may be viewed as a mean-field version of the Lévy-Lorentz gas, namely a 1-d model characterized…
