A toolbox of spin-adapted generalized Pauli constraints
Julia Liebert, Yannick Lemke, Murat Altunbulak +3
We establish a toolbox for studying and applying spin-adapted generalized Pauli constraints (GPCs) in few-electron quantum systems. By exploiting the spin symmetry of realistic …
Generalized Pauli constraints in small atoms
Christian Schilling, Murat Altunbulak, Stefan Knecht +5
The natural occupation numbers of fermionic systems are subject to non-trivial constraints, which include and extend the original Pauli principle. A recent mathematical breakthroug…
The Pauli principle revisited
M. Altunbulak, A. Klyachko
By the Pauli exclusion principle no quantum state can be occupied by more than one electron. One can put it as a constraint on the electron density matrix that bounds its eigenvalu…
