Square of Brownian motion [PDF]

open access: bronzeNagoya Mathematical Journal, 1975
Let Xt be a stochastic process and Yt be its square process. The present note is concerned with the solution of the equation assuming Yt is given. In [4], F. A. Grünbaum proved that certain statistics of Yt are enough to determine those of Xt when it is a centered, nonvanishing, Gaussian process with continuous correlation function. In connection with

A modified Φ-Sobolev inequality for canonical Lévy processes and its applications

open access: yesModern Stochastics: Theory and Applications, 2023
A new modified Φ-Sobolev inequality for canonical ${L^{2}}$-Lévy processes, which are hybrid cases of the Brownian motion and pure jump-Lévy processes, is developed.

Scaled Brownian motion with renewal resetting. [PDF]

open access: yesPhysical Review E, 2018
We investigate an intermittent stochastic process in which the diffusive motion with time-dependent diffusion coefficient D(t)∼t^{α-1} with α>0 (scaled Brownian motion) is stochastically reset to its initial position, and starts anew. In the present work

Development of a Self-Viscosity and Temperature-Compensated Technique for Highly Stable and Highly Sensitive Bead-Based Diffusometry

open access: yesBiosensors, 2022
Brownian motion, which is a natural phenomenon, has attracted numerous researchers and received extensive studies over the past decades. The effort contributes to the discovery of optical diffusometry, which is commonly used for micro/nano particle ...

Hot Brownian Motion [PDF]

open access: yesPhysical Review Letters, 2010
We derive the generalized Markovian description for the non-equilibrium Brownian motion of a heated particle in a simple solvent with a temperature-dependent viscosity. Our analytical results for the generalized fluctuation-dissipation and Stokes-Einstein relations compare favorably with measurements of laser-heated gold nano-particles and provide a ...

Properties of additive functionals of Brownian motion with resetting [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2018
We study the distribution of additive functionals of reset Brownian motion, a variation of normal Brownian motion in which the path is interrupted at a given rate and placed back to a given reset position.

An optimal polynomial approximation of Brownian motion [PDF]

open access: yes, 2020
In this paper, we will present a strong (or pathwise) approximation of standard Brownian motion by a class of orthogonal polynomials. The coefficients that are obtained from the expansion of Brownian motion in this polynomial basis are independent ...

Active Brownian motion in two dimensions [PDF]

open access: yesPhysical Review E, 2018
We study the dynamics of a single active Brownian particle (ABP) in two spatial dimensions. The ABP has an intrinsic timescale ${D}_{R}^{\ensuremath{-}1}$ set by the rotational diffusion constant ${D}_{R}$. We show that, at short times $t\ensuremath{\ll}{
