CHEMISTRY GLOSSARY Brownian motion Braunovo gibanje Brownian motion is the continuous random movement of small particles suspended in a fluid, which arise from collisions with the fluid molecules. First observed by the British botanist R. Brown (1773-1858) when studying pollen particles. The effect ...
Brown·i·an motion (brou′nē-ən) n. The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Also called Brownian movement. [After Robert Brown.] American Heritage® Dictionary of the English Language, Fifth...

The motion of the particles is produced by an alternating magnetic field applied perpendicular to the surface of the container. The mean square displacement of the particles is measured for a range of low concentrations and it is found that following an appropriate scaling of length and time, ...
Brownian motion is a phenomenon in which small particles suspended in a liquid tend to move in pseudo-random paths through the...

Nelson [7] presented an existentialist interpretation of stochastic mechanics. In Nelson’s theory, particles undergo Brownian motion (BM) as a result of a stochastic process, yielding the Schrödinger equation. One of the major drawbacks of Nelson’s theory is that it cannot explain the failure...
Scaled Brownian motion with α > 0. The overdamped SBM Langevin equation with time dependent diffusion coefficient D (t) tα−1 and α > 0 is typically used as the definition of SBM54–58, dx (t) = 2D(t) ×ζ (t). dt Here we consider the time dependent ...
The limit ω0=0 represents translational (free) Brownian motion. The earlier work (Hakim and Ambegaokar in Phys Rev A 32:423, 1985) concluded that the so defined limit transition is prohibited for spectral densities with s<2. In the present study we demonstrate that a specially constructed...
extended to a much broader class of fluid/solid couples. However, such generalization must be performed with caution as there are a number of limitations which can lead to departure from the simple intermittent Brownian motion at the heart of our approach. Depending on the nature of the ...
