Abstract
Ämnesord
Stäng
- This paper extends previous numerical studies on ficticious adaptive mass algorithms for Car-Parrinello and Ehrenfest dynamics to problems with more than two electron states. The main conclusion in this work is that it is necessary to resolve the near avoided conicial intersections between all electron eigenvalue gaps, also beween occupied states.
