Overview of Seniority Isomers [PDF]
Symmetry, 2022 Nuclear isomers are the metastable excited states of nuclei. The isomers can be categorized into a few classes including spin, seniority, K, shape and fission isomers depending upon the hindrance mechanisms.

Generalized seniority isomers in and around Z = 82 closed shell: A survey of Hg, Pb and Po isotopes [PDF]
Nuclear Physics A, 2021 In this paper, we investigate the generalized seniority scheme and the validity of Generalized Seniority Schmidt Model in and around the Z = 82 semi-magic region.

Seniority and Hierarchy Configuration Interaction for Radicals and Excited States. [PDF]
Journal of Chemical Theory and Computation, 2023 Hierarchy configuration interaction (hCI) has recently been introduced as an alternative configuration interaction (CI) route combining excitation degree and seniority number and has been shown to efficiently recover both dynamic and static correlations ...

Near-exact treatment of seniority-zero ground and excited states with a Richardson-Gaudin mean-field. [PDF]
Journal of Chemical Physics, 2022 Eigenvectors of the reduced Bardeen-Cooper-Schrieffer (BCS) Hamiltonian, Richardson-Gaudin (RG) states, are used as a variational wavefunction ansatz for strongly correlated electronic systems.

Hierarchy Configuration Interaction: Combining Seniority Number and Excitation Degree [PDF]
Journal of Physical Chemistry Letters, 2022 We propose a novel partitioning of the Hilbert space, hierarchy configuration interaction (hCI), where the excitation degree (with respect to a given reference determinant) and the seniority number (i.e., the number of unpaired electrons) are combined in

Reduced density matrix functional theory from an ab initio seniority-zero wave function: Exact and approximate formulations along adiabatic connection paths [PDF]
Physical Review A, 2022 Currently, there is a growing interest in the development of a new hierarchy of methods based on the concept of seniority, which has been introduced quite recently in quantum chemistry.

Density matrices of seniority-zero geminal wavefunctions. [PDF]
Journal of Chemical Physics, 2022 Scalar products and density matrix elements of closed-shell pair geminal wavefunctions are evaluated directly in terms of the pair amplitudes, resulting in an analog of Wick's theorem for fermions or bosons.
