Phonon Renormalization: Harmonic phonons that are directly calculated using DFT-based methods at 0 K are effectively modified at higher temperatures as atomic displacements reach beyond the harmonic region. Most prominent of such an effect is the stabilization of otherwise dynamically unstable materials at 0 K (imaginary phonon frequencies), which may lead to phase transitions. This not only has a direct consequence for functionalities such as ferroelectricity and shape memory, but also affects the analysis of other thermal properties derived from phonons including lattice thermal conductivity. Several available methods can calculate effective TD phonons. SCAILD (Self-consistent ab initio Lattice Dynamics) iteratively updates harmonic frequencies via temperaturedependent, normal-mode displacements of atoms . QSCAILD (Quantum SCAILD) improves upon it by using the so-called quantum covariance of atomic displacements accounting for quantum motion to sample atomic configurations , and use these to obtain effective harmonic IFC. SSCHA (Stochastic Self-consistent Harmonic Approximation) finds IFCs that minimize harmonic free energy at a given temperature . TDEP (Temperature Dependent Effective Potential) uses AIMD simulations for sampling temperature-dependent configurations, followed by fitting effective IFCs . Though these represent accurate and reliable approaches, all of them by their standard protocol invoke DFT calculations after every iteration of ensemble generation to compute energies and forces. For high-throughput deployment, a higher computational efficiency is essential.
