SUMMARY

This discussion focuses on writing an input file for rutile TiO2 using Quantum ESPRESSO. Key points include the importance of accurately determining atomic positions, bond lengths, and bond angles, which should be sourced from experimental data such as X-ray diffraction (XRD) results. Participants emphasize the necessity of mapping these values into K space to identify K-points and K-paths for energy calculations in Quantum ESPRESSO. The conversation highlights the integration of experimental data with computational methods for effective modeling.

I assume that the atomic positions (including bond length and bond angle) would come from experiments such as XRD. We take these values (may be from journals where such results are published) and then map them into K space, to find the K-points/K-path along which the energy is calculated using quantum espresso or other tools.
