Query: Brownian dynamics simulations to explore experimental microsphere
  diffusion with optical tweezers   We develop two-dimensional Brownian dynamics simulations to examine the
motion of disks under thermal fluctuations and Hookean forces. Our simulations
are designed to be experimental-like, since the experimental conditions define
the available time-scales which characterize the solution of Langevin
equations. To define the fluid model and methodology, we explain the basics of
the theory of Brownian motion applicable to quasi-twodimensional diffusion of
optically-trapped microspheres. Using the data produced by the simulations, we
propose an alternative methodology to calculate diffusion coefficients. We
obtain that, using typical input parameters in video-microscopy experiments,
the averaged values of the diffusion coefficient differ from the theoretical
one less than a 1\%.
