Exact solution of spherical mean-field plus a special orbit-dependent non-separable pairing Hamiltonian with multi non-degenerate j-orbits, which is related to two previously known hyperbolic Gaudin models, is explored. It is shown that the Hamiltoni

A diagonalization scheme for the shell model mean-field plus isovector pairing Hamiltonian in the O(5) tensor product basis of the quasi-spin SUΛ(2) ⊗ SUI(2) chain is proposed. The advantage of the diagonalization scheme lies in the fact that not

New polynomials related to the mean-field plus isovector pairing model are constructed based on the Stieltjes correspondence. It is shown that there is an one-to-one correspondence between zeros of the two related extended Heine-Stieltjes polynomials

An algebraic framework for carrying out detailed shell model calculations in a SU(3) basis is introduced and applied to various sets of ds-shell valence nucleons bound in a shell model mean-field with residual quadrupole–quadrupole and pairing inte

An extended ${\mathrm{O}}_{\mathcal{S}T}$(8) model with multi-$j$ orbits is constructed based on the angular momentum decomposition with ``pseudo''-spin $\mathcal{S}$ for valence nucleons in a $j$ orbit. It is shown that the isovector $\mathcal{S}=0$

The competition of isovector and isoscalar pairing in A=18 and 20 even-even N≈Z nuclei is analyzed in the framework of the mean-field plus the dynamic quadurpole-quadurpole, pairing and particle-hole interactions, whose Hamiltonian is diagonalized
