Phonopy primitive_axis
WebThe present invention is to determine abnormalities of organs or muscles in the body. A method for determining abnormalities in organs or muscles in the body comprises the steps of: acquiring at least one image for organs or muscles in the body; determining at least one characteristic matrix for the at least one image; determining a specific value for … 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.
