WebNov 2, 2024 · As part of the process of "vetting" the potential, they require that all the phonon frequencies are real; in other words, all the "spring constants" are positive. Otherwise, a simple deformation with the corresponding wave-vector would lower the potential energy, so the proposed crystal structure would be mechanically unstable.
