WebJul 8, 2024 · When phonopy (or any similar calculation technique) finds displacements in the cell based on symmetry, the idea is to see how the displacement of certain ions affects the forces on every ion within the cell. We must then take care that the displaced ions don't affect themselves i.e. the effect of their displacement doesn't interact with itself. http://muchong.com/html/201412/8336507.html flocked vinyl heat transfer hobby lobby
