Symmetry-driven correlation patterns in one-dimensional periodic fermionic systems: Closed-form expressions and exact selection rules for correlation functions, entanglement entropies, and mutual information

We present an analytical study of the spatial structure of correlations in periodic fermionic systems at the single Slater determinant level, focusing on the cyclic case. Exploiting cyclic symmetry, the transformation from localized orbitals to molecular orbitals is simultaneousl...
