OMR-NPA: Optimized Matrix Representation of Nucleon Pair Approximation
Y. Lei, Y. Lu
We optimize the matrix representation of the nucleon-pair approximation (NPA) of the nuclear shell model. The NPA is a widely adopted truncation approach of the nuclear shell model…
Nuclear states projected from a pair condensate
Yi Lu, Yang Lei, Calvin W. Johnson +1
Atomic nuclei exhibit deformation, pairing correlations, and rotational symmetries. To meet these competing demands in a computationally tractable formalism, we revisit the use of…
Nucleon-pair approximation with matrix representation
Y. Lei, Y. Lu, Y. M. Zhao
In this paper, we propose an approach of the nucleon-pair approximation (NPA), in which the collective nucleon pairs are represented in terms of antisymmetric matrices, and commuta…
Variational approach for pair optimization in the nucleon pair approximation
Y. Lei, H. Jiang, S. Pittel
We propose a pair-condensate variational approach (PCV) to determine a set of the most important collective pairs in the description of low-lying states in atomic nuclei. Having av…
Random-interaction study on linear systematics of electromagnetic moments in Cd isotope chain
Z. Z. Qin, Y. Lei
In the random-interaction ensembles, electromagnetic moments of Cd isomers predominately present linear systematics as changing the neutron number, which has been repo…
From local correlations to regional systematics
Z. Z. Q, M. Bao, Y. Lei
Local correlations of excitation energies and B(E2, ) values require linear systematics in a logarithmic scale, as confirmed by an e…
