Implications of pinned occupation numbers for natural orbital expansions. II: rigorous derivation and extension to non-fermionic systems

Implications of pinned occupation numbers for natural orbital expansions. II: rigorous derivation and extension to non-fermionic systems

We have explained and comprehensively illustrated in Part I (Schilling et al 2019 arXiv: http://1908.10938 ) that the generalized Pauli constraints suggest a natural extension of the concept of active spaces. In the present Part I (Schilling et al 2019 arXiv: http://1908.10938 )I, we provide rigorou...
