Pwscf Inputs


This is my small collection of Quantum Espresso (PWSCF) and Yambo input files that I used in my papers or for different testing purposes. If you desperately need it, it can be quite easily implemented if you provide working sample inputs for all possible space groups and settings, preferably along with cif files corresponding to that input (that's the 16 cases listed in the pwscf manual for the ibrav keyword). • CP (Car-Parrinello). It consists in the total energy calculation of a 5 atom cubic cell of BaTiO 3. A future release will remove babel entirely. Principal IT Investigators.
