GAP interatomic potential for gold

Gaussian approximation potential (GAP) for gold [1]. It has been fitted with QUIP/GAP [1,2] by generating a new database of atomic structures containing:

1. dimers;
2. fcc, bcc, hcp and simple-cubic supercells, including strained, distorted and high-temperature configurations;
3. surface slabs;
4. clusters.

The calculations were carried out at the PBE level of theory [3] using the VASP code [4,5]. This potential uses 2-body (distance_2b) and SOAP-type descriptors (soap_turbo) [6,7], as implemented in the TurboGAP code [8]. The files can be used both with QUIP/GAP (compiled with the soap_turbo libraries) and TurboGAP. When using this potential, please read and cite:
