Brownian motion of skyrmion bubbles and its control by voltage applications
Applied Physics Letters, 2019Magnetic skyrmions are expected to be promising candidates for information carriers in spintronic devices. In previous work, precise position control of skyrmions has been the main focus of attention for memory and logic applications.

Battery Health Prognosis Using Brownian Motion Modeling and Particle Filtering
IEEE transactions on industrial electronics (1982. Print), 2018The prognostics and health management of lithium-ion batteries is extremely important for the working performance and cost of energy storage systems. Accurately forecasting battery state of health (SOH) and remaining useful life (RUL) plays an important ...

On the Theory of the Brownian Motion
, 1930With a method first indicated by Ornstein the mean values of all the powers of the velocity $u$ and the displacement $s$ of a free particle in Brownian motion are calculated. It is shown that $u\ensuremath{-}{u}_{0}\mathrm{exp}(\ensuremath{-}\ensuremath{\

On the theory of brownian motion
, 1973The spectrum of the Fokker-Planck operator for weakly coupled gases is considered. The operator is decomposed into operators acting on functions whose angular dependence is given by spherical harmonics.

Physical Review Letters, 1983
A new master equation describing the irreversible process of a quantum mechanical Brownian particle is proposed. The master equation is shown to obey the symmetry of detailed balance leading to a quantum analog of the reciprocity relations, and the fluctuation-dissipation theorem is obtained. The method is applied to the damped harmonic oscillator. The

This chapter provides an introduction to the main ideas of Brownian motion. Brownian motion connects equilibrium and nonequilibrium statistical mechanics. It connects diffusion—a nonequilibrium phenomenon—with thermal fluctuations—an equilibrium concept.

Catastrophes in Brownian motion
Physics Letters A, 2003Abstract We consider the motion of a Brownian particle in a tilted periodic potential with a fluctuating phase. The fluctuations are supposed to be either a nonstationary diffusion stochastic process or an Ornstein–Uhlenbeck process. In the latter case, the problem can be reduced to a system driven by additive “green” noise [Phys. Lett.

Publisher Summary This chapter discusses the Brownian motion, and reviews the construction of the Brownian motion. The simplest properties of the Brownian motion are discussed. A Martingale inequality is discussed, and the law of the iterated logarithm is reviewed. Several-dimensional Brownian motion is also discussed in the chapter.

Role of Brownian motion in the enhanced thermal conductivity of nanofluids
, 2004We have found that the Brownian motion of nanoparticles at the molecular and nanoscale level is a key mechanism governing the thermal behavior of nanoparticle–fluid suspensions (“nanofluids”).

Reflected Brownian Motions [PDF]
, 1983 The process \( |B| \) is called the reflection of the Brownian motion B at zero. By (8.1), the pair \( (|B|,L) \) is almost surely the solution of a certain problem of reflection for \( \hat{B} \), discussed in Section 8.2. This yields an alternative representation, directly in terms of \( \hat{B} \), for L and hence for \( |B| \) The Ito formula will ...
