WebJan 21, 2024 · As for excited states: The Casida formalism is currently based on the 2nd order DFTB formalism. In earlier versions, we did not implement checks for preventing setting Casida and 3rd order together. As a result, ground state Hamiltonian contained the 3rd order term, but the excitations only the 2nd order one. WebThe DFTB module can treat molecular as well as periodic systems (1D for nanotubes, 2D for surfaces, 3D for bulk), and as such can be used as a fast pre-optimizer for full molecular …

WebJan 5, 2024 · The most recent and important development in DFTB is the long-range corrected DFTB (LC-DFTB). The first two practical implementation and benchmark studies were reported in 2015 by Humeniuk et al. [ 27 ] and Lutsker et al. [ 28 ], although the initial formulation was outlined in 2012 by a coauthor of the latter study [ 29 ].
