Algorithms for brownian dynamics
Abstract
A third order algorithm for brownian dynamics (BD) simulations is proposed, which is identical to the powerful molecular dynamics (MD) algorithm due to Verlet in the limit of infinitely small friction coefficient γ. In contrast to most BD algorithms used up till now, the integration time step Δt is not limited by the condition Δt ≪ γ-1. It is shown how constraints, such as bondlength or bond angle constraints, can be incorporated in the computational scheme. For the molecule considered here the proposed BD algorithm is about ten times more efficient than the second order ones that are generally used. The introduction of bondlength constraints saves about a factor of three in computing time, as in the MD case. The application of bond angle constraints is not recommended.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
