Perturbed second derivative multistep methods

Journal of Numerical Mathematics, 2015
AbstractExtended second derivative multistep methods and their modified form have been introduced as efficient numerical solvers for stiff systems. Considering these methods from second derivative general linear methods point of view, we construct some perturbations of these methods which improve their stability properties while preserve their order ...

Second derivatives for approximate spin projection methods

The Journal of Chemical Physics, 2015
The use of broken-symmetry electronic structure methods is required in order to obtain correct behavior of electronically strained open-shell systems, such as transition states, biradicals, and transition metals. This approach often has issues with spin contamination, which can lead to significant errors in predicted energies, geometries, and ...
