Web2 de mai. de 2024 · The idea in solving this problem is to represent the sum B ( s) + B ( t) as the sum of an increment. That is, B ( s) + B ( t) = 2 B ( s) + B ( t) − B ( s) and since we know incrememnts of a brownian motion are independent, then 2 B ( s) is independent of B ( t) − B ( s). Thus, we can easily get that E [ B ( s) + B ( t)] = 0 & V a r [ B ( s ... WebIn this paper, we employ a mean-field linear stability analysis as well as Brownian dynamics simulations to study the effect of thermal motion on the onset of instability. We find that in the absence of electric fields, Brownian motion consistently suppresses instability formation through randomization of particle orientation.
