Files Two files per system, named _: _train.xyz – training set in extended XYZ format, with reference energies, forces and virials. _nep.txt – the NEP potential, usable directly with GPUMD or calorine. Systems PbTiO3 – 345 structures, 5–320 atoms per structure, reference method VASP with r2SCAN. CsGeBr3 – 110 structures, 5–160 atoms per structure, reference method FHI-aims with r2SCAN50. CsSnBr3 – 103 structures, 5–320 atoms per structure, reference method FHI-aims with r2SCAN50. Potentials All three are fourth-generation NEPs with charge support (charge_mode 1, lambda_q 0.1), three species, radial and angular cutoffs of 8 and 4 Å, trained for 300 000 generations. The two halides additionally use a ZBL repulsive term. Access to data through an external actor. Data are freely accessible. Åtkomst till data via extern aktör. Data är fritt tillgängliga. openAccess
