Figure 7. Comparison of the phonon dispersion of HCP Zn calculated from (A) DP, (B) MEAM, and (C) ANN, compared with the DFT (PBE) and (D) experimental values. HCP: Hexagonal close-packed; DP: Deep Potential; MEAM: Modified Embedded-Atom Method; ANN: artificial neural network; DFT: Density Functional Theory; PBE: Perdew-Burke-Ernzerhof; Exp.: experimental.
