A spectral neighbor analysis potential for Mo. The potential is trained against diverse and large materials data, including bulk bcc Mo, strained bcc Mo, ab-initio molecular dynamics (AIMD) simulated random structures, melted structures, vacancy-containing structures, surfaces, grain boundaries, strained melted structures. The potential gives accurate predictions of structural energies, forces, stresses, elasticity, lattice parameters, vacancy migration barrier, equation-of-state, phonon, free energies, melting point, surface energies, and grain boundary energies.
