The default plane-wave basis set and integration grid are determined by `cell.mesh`, +but these can be customized using the energy cutoffs `ecut_wf` and `ecut_rho` or by setting +meshes directly using `PWKSCF.set_meshes()`. + +The following post-SCF calculations are supported: +* MP2 (Restricted and Unrestricted) +* CCSD (Restricted only) + +K-point symmetry and occupation smearing are currently not supported for post-SCF +methods. The `PWKSCF.get_cpw_virtual()` method can be used to create virtual +molecular orbitals in a GTO basis for use in post-SCF calculations. + +Plane-wave calculations can be performed with GTH or CCECP pseudopotentials +(or all-electron for very small atoms). There is also basic support for SG15 +norm-conserving pseudopotentials. The post-SCF methods have been tested with GTH +and CCECP but not SG15, while the SCF methods have been tested with GTH, CCECP, and SG15.
