TL;DR: In this paper, the free energy of a defect-free hard-sphere crystal with a fixed center of mass was analyzed and the remaining free energy was found to depend linearly on 1/N.

TL;DR: In this article, the free energy of a defect-free hard-sphere crystal of particles interacting through an r-12 potential is estimated. But this is not the case for an equilibrium hardsphere with a fixed center of mass.

TL;DR: In this paper, the authors examine the performance of various commonly used integration schemes in dissipative particle dynamics simulations and find that the best overall performance is for integrators in which the velocity dependence of dissipative forces is taken into account, and particularly good performance is found for an approach in which velocities and dissipative force are determined self-consistently.

TL;DR: In this paper, the authors examine the performance of various commonly used integration schemes in dissipative particle dynamics simulations and find that many commonly used integrators may give rise to surprisingly pronounced artifacts in physical observables such as the radial distribution function, the compressibility, and the tracer diffusion coefficient.

TL;DR: It is demonstrated that commonly used integration schemes in dissipative particle dynamics give rise to pronounced artifacts in physical quantities such as the compressibility and the diffusion coefficient.
