In the simulations, random numbers following this distribution are generated using the Box-Muller method, and these are used to determine the random displacements. The temperature 𝑇 in the random force is approximated as room temperature 𝑇 𝑟𝑜𝑜𝑚 . Furthermore, when calculating Brownian motion displacement, same seed values of random numbers are used for every simulation run to focus on the effect other than randomness.
