Perhaps you should try some spelling variations:
eu ansatzes » des ansatzes, neuen ansatzes, news ansatzes
yang guang » yang yang, yan guan, yang liang
ansatzes 2 » ansatze 2, ansatze _, ansatze 3
zhong tai » hong tan, hong hai, zhong zhi
nan yang » dan yang, nan yan, tan yang
dong di » dong sin
2 j » 2 ja, 72 j

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: nan yang guang eu ansatzes 2 j ((zhong tai) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yang guang eu ansatzes 2 j ((zhong tai) or (dong di)) ;*.
