You might be overthinking things if the system looks like what I expect it does. You can calculate all the terms for the platinum and subtract out their contribution, this is perfectly fine if you ...

### Need help about how I can get/generate semicore pseudopotentials to be used in Quantum Espresso DFT?

There are many pseudopotential libraries available to choose from. Below is a (most definitely incomplete) list of pseudopotential libraries compatible with Quantum ESPRESSO that are either curated or ...

Usually for an isolated species, you would just compute the vibrational modes (phonon modes) at the gamma point and sum the modes to compute the molecular ZPE  E^{ZP} = \frac{h}{2} \sum_{i=1}^{3N-6} ...

With the help of the PW forum and after digging a bit, I have gained some understanding of what went wrong. My job had "way too many processes spanning way too many threads for a single node.&...
