WebJun 13, 2024 · Longer answer: The starting point of any phonon calculation is the Born-Oppenheimer approximation, which allows you to separate the electron and nuclear degrees of freedom. After applying this Born-Oppenheimer approximation, you end up with two eigenvalue equations. WebFor using phonopy first you have to optimize your structure with any phonopy supporting code like VASP, WIEN2k, ABINIT etc. After that post process your required results with phonopy. All...
WebPhonopy will create the supercells with the displacements needed, and all you have to do is compute either the FORCES (IBRION=-1) or Hessian/FORCE CONSTANTS (IBRION=-5).
