Dear CP2K Users,<div><br /></div><div>I am currently working on a project involving the adsorption model </div><div>of NO on an Au(111) slab using CP2K. During the standard GPW </div><div>calculation, I receive the following components of the total energy:<br /><div><br /></div><div>Overlap energy of core charge distribution </div><div>Self-energy of the core charge distribution </div><div>Core Hamiltonian energy </div><div>Hartree energy </div><div>Exchange-correlation energy<br /></div><div><br /></div><div>While summing up these components will give me the total energy, </div><div>I have come across literature suggesting an alternative method to </div><div>obtain the total energy using the KS eigenvalues and occupations.</div><div>It is stated that the sum of occupied eigenvalues and the so-called </div><div>"double counting terms" can yield the total energy. "double counting</div><div>terms" including negative "Hartree energy", "XC energy" and negative</div><div>"XC potential".</div><div><br /></div><div><img alt="WeChat77d505e070ffb01052d0ec6a5c0aaeb0.jpg" width="534px" height="105px" src="cid:c2315784-ff5e-4421-b92f-c8deac3eeeaa" /><br /></div><div><br /></div><div>I know I can obtain the eigenvalues and occupations by, for example,</div><div>outputting the PDOS. However, I don't know how to get the "double </div><div>counting terms" in CP2K, particularly, the "XC potential" term.</div><div><br /></div><div>I am writing to inquire whether CP2K can provide these energies, </div><div>and if so, I would greatly appreciate guidance on how to adjust my </div><div>input accordingly. For your reference, I have attached my input file below.<br /></div><div><br /></div><div>Thank you very much for your assistance and insights.</div><div><br /></div><div>Best Reguards, </div><div>Rui-Hao</div></div>
