Moment Tensor Potentials: A Class of Systematically Improvable Interatomic Potentials

Density functional theory offers a very accurate way of computing materials properties from first principles. However, it is too expensive for modeling large-scale molecular systems whose properties are, in contrast, computed using interatomic potentials. The present paper considers, from a mathematical point of view, the problem of constructing interatomic potentials that approximate a given q...

Interatomic potentials for materials with interacting electrons

Evidence for the significant part played by magnetism in the picture of interatomic interactions in iron and iron-based alloys has recently emerged from density functional studies of the structure of radiation induced defects. In this paper we examine the range of validity of the currently available model interatomic potentials for magnetic iron, investigate the effect of electron–electron inte...

Empirical interatomic potentials optimized for phonon properties

Molecular dynamics simulations have been extensively used to study phonons and gain insight, but direct comparisons to experimental data are often difficult, due to a lack of accurate empirical interatomic potentials for different systems. As a result, this issue has become a major barrier to realizing the promise associated with advanced atomistic-level modeling techniques. Here, we present a ...

Interatomic bond-order potentials and structural prediction

Interatomic bond-order potentials (BOPs) have recently been derived for covalently bonded systems whose electronic structure is well described by the tight-binding (TB) approximation. This paper introduces the key ideas behind this novel class of interatomic potentials through a case study of the factors controlling the relative structural stability of s-valent four-atom clusters with respect t...

Role of Interatomic Potentials in Simulation of Thermal Transport in Carbon Nanotubes

Interatomic potentials, which describe interactions between elements of nanosystems, are crucial in theoretical study of their physical properties. We focus on two well known empirical potentials, i.e. Tersoff's and Brenner's potentials, and compare their performance in calculation of thermal transport in carbon nanotubes. In this way, we study the temperature and diameter dependence of thermal...
