<div>Dear Niharendu,</div><div><br></div><div>The code works with any element and all GTH-pseudo potentials and suitable basis sets.<br></div><div><br></div><div>Basis sets and pseudo potentials are generally available in the cp2k/data directory. Just grep for the required elements. In case of MP2, I strongly recommend correlation-consistent basis sets. We have a RI-MP2-based implementation and a canonical MP2 implementation. The first one also allows gradient calculation, the latter does not.</div><div><br></div><div>In case of actinides, I am aware of ECPs for these elements, but I am not familiar with their usage. There are pseudopotentials available optimized with PBE but I guess that they are not suitable for MP2 calculations. You may try to optimize them yourself with our atom code.<br></div><div><br></div><div>I am not aware of correlation-consistent basis sets for actinides which can be used with pseudopotential calculations. Either, there are already publications with suitable basis sets or you have to optimize them yourself.</div><div><br></div><div>In case of RI-MP2, you will also need RI basis sets which are definitely not available for actinides. But you can use the automatically generated RI basis sets (keyword AUTO_BASIS).</div><div><br></div><div>Best,</div><div>Frederick<br></div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr">nihar...@gmail.com schrieb am Dienstag, 6.
