Perhaps you should try some spelling variations:
quantum dynamisches » quantum dynamics, quantum dynamical, quantum dynamic
dynamisches system » dynamischer systeme, dynamische systeme, dynamical system
quantum chemical » quantum mechanical, quantum chemistry
chemical system » chemical systems, biochemical systems, dynamical system

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( quantum chemical system ) OR ( quantum dynamisches system )).
• Adding a wildcard symbol may retrieve word variants: (( quantum chemical system ) or ( quantum dynamisches system ))*.
