Optimal estimates of diffusion coefficients from molecular dynamics simulations

  title={Optimal estimates of diffusion coefficients from molecular dynamics simulations},
  author={Jakob T{\'o}mas Bullerjahn and Soren von Bulow and Gerhard Hummer},
Translational diffusion coefficients are routinely estimated from molecular dynamics simulations. Linear fits to mean squared displacement (MSD) curves have become the de facto standard, from simple liquids to complex biomacromolecules. Nonlinearities in MSD curves at short times are handled with a wide variety of ad hoc practices, such as partial and piece-wise fitting of the data. Here, we present a rigorous framework to obtain reliable estimates of the diffusion coefficient and its…

Optimal estimation of diffusion coefficients from single-particle trajectories.

An explicit, unbiased, and practically optimal covariance-based estimator that is regression-free and far superior to commonly used methods based on measured mean squared displacements, and outperforms the analytically intractable and computationally more demanding maximum likelihood estimator (MLE).

System-Size Dependence of Diffusion Coefficients and Viscosities from Molecular Dynamics Simulations with Periodic Boundary Conditions

We study the system-size dependence of translational diffusion coefficients and viscosities in molecular dynamics simulations under periodic boundary conditions. Simulations of water under ambient

Dynamic cluster formation determines viscosity and diffusion in dense protein solutions

The consistency between simulations and experiments for a diverse set of soluble globular proteins indicates that the cluster model applies broadly to concentrated protein solutions, with equilibrium dissociation constants for nonspecific protein–protein binding in the Kd ≈ 10-mM regime.

Pressure and temperature dependence of self-diffusion in water

The self-diffusion coefficient, D, for pure liquid water has been measured at temperatures between 275.2 and 498.2 K and at pressures up to 1.75 kbar by the proton spin echo method. Our values of D

Model Comparison and Assessment for Single Particle Tracking in Biological Fluids

ABSTRACT State-of-the-art techniques in passive particle-tracking microscopy provide high-resolution path trajectories of diverse foreign particles in biological fluids. For particles on the order of

This paper derives a convenient and asymptotically optimal maximum likelihood estimator for the diffusion coefficient and for the magnitude of localization noise together with the corresponding Fisher information, which bounds the performance of all unbiased estimators.

Hydrodynamics of Diffusion in Lipid Membrane Simulations.

By performing molecular dynamics simulations with up to 132 million coarse-grained particles in half-micron sized boxes, we show that hydrodynamics quantitatively explains the finite-size effects on

Polymorphic transitions in single crystals: A new molecular dynamics method

A new Lagrangian formulation is introduced. It can be used to make molecular dynamics (MD) calculations on systems under the most general, externally applied, conditions of stress. In this
