Refining ensemble -representability of one-body density matrices from partial information
Julia Liebert, Anna O. Schouten, Irma Avdic +2
The -representability problem places fundamental constraints on reduced density matrices (RDMs) that originate from physical many-fermion quantum states. Motivated by recent dev…
Spin adaptation of the cumulant expansions of reduced density matrices
Julia Liebert, Christian Schilling, David A. Mazziotti
We develop a systematic framework for the spin adaptation of the cumulants of p-particle reduced density matrices (RDMs), with explicit constructions for p = 1 to 3. These spin-ada…
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 …
