Reduced basis emulation of pairing in finite systems
Virgil V. Baran, Denis R. Nichita
In recent years, reduced basis methods (RBMs) have been adapted to the many-body eigenvalue problem and they have been used, largely in nuclear physics, as fast emulators able to b…

Structure of the quartetting ground state of nuclei
A. G. Serban, D. R. Nichita, D. Negrea +1
The formal equivalence between the quartetting picture and the symmetry restored BCS picture is established for the ground state correlations induced by the general isovector-isosc…

Bridging the quartet and pair pictures of isovector proton-neutron pairing
V. V. Baran, D. R. Nichita, D. Negrea +3
The formal implications of a quartet coherent state ansatz for proton-neutron pairing are analyzed. Its nonlinear annihilation operators, which generalize the BCS linear quasiparti…
