WebJan 10, 2024 · Another way to obtain the lattice specific heat is based on ab initio calculations. Density functional theory (DFT) calculations allow one to obtain all the phonon modes of a crystal, while the lattice specific heat could be calculated from phonon density of states within the quasi-harmonic approximation [5, 6]. WebDFT belongs to the family of first principles (ab initio) methods, so named because they …

WebJan 1, 2012 · Abstract. In this chapter, an introduction to ab initio molecular dynamics (AIMD) has been given. Many of the basic concepts, like the Hellman–Feynman forces, the difference between the Car–Parrinello molecular dynamics and AIMD, have been explained. Also a very versatile AIMD code, the CP2K, has been introduced.
