Phonopy force set
WebIJ is the matrix of inter-atomic force constants, i.e. second derivatives of the energy with respect to atomic positions: Cαβ IJ ≡ ∂2E({R}) ∂Rα I ∂R β J = − ∂F αI({R}) ∂Rβ J In crystals, normal modes are classified by a wave-vector q. Phonon frequencies, ω(q), and displacement patterns, Uα s (q), are determined by the ... WebTo obtain supercells ( 2 × 2 × 2) with displacements, run phonopy: phonopy setting.conf --abacus -d. Calculate forces on atoms in the supercells with displacements. For each SCF calculation, you should specify stru_file with STRU- {number} and cal_force=1 in INPUT in order to calculate force using ABACUS. Be careful not to relax the structures.
