Entropy corrected geometric Brownian motion

R Gupta, EA Drzazga-Szczȩśniak, S Kais… - Scientific Reports, 2024 - nature.com
The geometric Brownian motion (GBM) is widely used for modeling stochastic processes,
particularly in finance. However, its solutions are constrained by the assumption that the …

Number of distinct sites visited by a resetting random walker

M Biroli, F Mori, SN Majumdar - Journal of Physics A …, 2022 - iopscience.iop.org
We investigate the number V p (n) of distinct sites visited by an n-step resetting random
walker on a d-dimensional hypercubic lattice with resetting probability p. In the case p= 0 …

Population heterogeneity in the fractional master equation, ensemble self-reinforcement, and strong memory effects

S Fedotov, D Han - Physical Review E, 2023 - APS
We formulate a fractional master equation in continuous time with random transition
probabilities across the population of random walkers such that the effective underlying …

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 …

Spectral design of anomalous diffusion

I Eliazar - Physica A: Statistical Mechanics and its Applications, 2023 - Elsevier
This paper poses and addresses the following goal: design a random motion that displays
one type of anomalous diffusion in real space, and another type of anomalous diffusion in …

First passage dynamics of stochastic motion in heterogeneous media driven by correlated white Gaussian and coloured non-Gaussian noises

NM Mutothya, Y Xu, Y Li, R Metzler… - Journal of Physics …, 2021 - iopscience.iop.org
We study the first passage dynamics for a diffusing particle experiencing a spatially varying
diffusion coefficient while driven by correlated additive Gaussian white noise and …

Big jump principle for heavy-tailed random walks with correlated increments

M Höll, E Barkai - The European Physical Journal B, 2021 - Springer
The big jump principle explains the emergence of extreme events for physical quantities
modelled by a sum of independent and identically distributed random variables which are …

Maximal Entropy Formalism for Quantum State Tomography and Applications

This thesis advances the methodologies of quantum state tomography (QST) to validate and
optimize quantum processing on Noisy Intermediate-Scale Quantum (NISQ) devices, crucial …

Discrete sampling of correlated random variables modifies the long-time behavior of their extreme value statistics

L Zarfaty, E Barkai, DA Kessler - arXiv preprint arXiv:2108.06778, 2021 - arxiv.org
We consider the extreme value statistics of correlated random variables that arise from a
Langevin equation. Recently, it was shown that the extreme values of the Ornstein …
