WebApr 26, 2024 · Often, TRAH-SCF finds a symmetry-broken solution with a lower energy than DIIS and KDIIS. For unrestricted calculations, this is accompanied by a larger spin contamination, i.e., larger deviation from the desired spin-restricted S 2 expectation value. However, there are also rare cases in which DIIS finds a solution with a lower energy than ...
