Implications of pinned occupation numbers for natural orbital expansions. I: Generalizing the concept of active spaces
Christian Schilling, Carlos L. Benavides-Riveros, Alexandre Lopes +2
The concept of active spaces simplifies the description of interacting quantum many-body systems by restricting to a neighbourhood of active orbitals around the Fermi level. The re…

On the time evolution of fermionic occupation numbers
Carlos L. Benavides-Riveros, Miguel A. L. Marques
We derive an equation for the time evolution of the natural occupation numbers for fermionic systems with more than two electrons. The evolution of such numbers is connected with t…
