On mean-field super-brownian motions
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.

But here I am interested in the average distance using only (+) signs! It's said the expected "spread" is √𝑝𝑞t (p,q .. probability for left,right, t.. time). Unfortunately I am not sure if "spread" is what I am ...
