We introduce a Gaussian approximation potential (GAP) for atomistic simulations of liquid and amorphous elemental carbon. Based on a machine learning representation of the density-functional theory (DFT) potential-energy surface, such interatomic potentials enable materials simulations with close-to DFT accuracy but at much lower computational cost. We first determine the maximum accuracy that any finite-range potential can achieve in carbon structures; then, using a hierarchical set of two… 
Machine Learning a General-Purpose Interatomic Potential for Silicon
The success of first principles electronic structure calculation for predictive modeling in chemistry, solid state physics, and materials science is constrained by the limitations on simulated length
Gaussian approximation potential modeling of lithium intercalation in carbon nanostructures.

Computational Surface Chemistry of Tetrahedral Amorphous Carbon by Combining Machine Learning and Density Functional Theory
Tetrahedral amorphous carbon (ta-C) is widely used for coatings because of its superior mechanical properties and has been suggested as an electrode material for detecting biomolecules. Despite
A machine-learned interatomic potential for silica and its relation to empirical models
Silica (SiO 2 ) is an abundant material with a wide range of applications. Despite much progress, the atomistic modelling of the different forms of silica has remained a challenge. Here we show that
Machine learning interatomic potential developed for molecular simulations on thermal properties of β-Ga2O3.
The successful application of the GAP model to the phonon density of states of a 2500-atom β-Ga2O3 structure at elevated temperature indicates the strength of machine learning potentials to tackle large-scale atomic systems in long molecular simulations, which would be almost impossible to generate with DFT-based molecular simulations at present.
Understanding the thermal properties of amorphous solids using machine-learning-based interatomic potentials
Abstract Understanding the thermal properties of disordered systems is of fundamental importance for condensed matter physics - and for practical applications as well. While quantities such as the
Data-Driven Learning of Total and Local Energies in Elemental Boron.
This model readily provides atom-resolved, local energies and thus deepened insight into the frustrated β-rhombohedral boron structure, and opens the door for the efficient and automated generation of GAPs, and other machine-learning-based interatomic potentials, to suggest their usefulness as a tool for materials discovery.
