Finding the best basis states for the variation after projection nuclear wave functions
Xiao Lu, Zhan-Jiang Lian, Xue-Wei Li +2
The variation after projection (VAP) method is expected to be an efficient way of getting the optimized nuclear wave functions, so that they can be as close as possible to the exac…

Xiao Lu, Zhan-Jiang Lian, Zao-Chun Gao
In this paper, we study the mixing of one-particle-one-hole projected states with the variation after projection (VAP) wave functions in attempt to improve the approximation of thi…
Removal of -mixing in angular momentum projected nuclear wave functions
Xiao Lu, Zhan-Jiang Lian, Zao-Chun Gao
Angular momentum projection plays a key role in studying quantum many-body systems with rotational invariance such as atomic nuclei. At a given spin , one can generate an…

We implemented a variation after projection (VAP) algorithm based on a triaxially deformed Hartree-Fock-Bogoliubov vacuum state. This is the first projected mean field study that i…
Description of collective and quasiparticle excitations in deformed actinide nuclei: The first application of the Heavy Shell Model
Ji-Wei Cui, Xian-Rong Zhou, Fang-Qi Chen +3
The Heavy Shell Model (HSM) (Y. Sun and C.-L. Wu, Phys. Rev. C 68, 024315 (2003)) was proposed to take the advantages of two existing models, the projected shell model (PSM) and th…
Matrix elements of one-body and two-body operators between arbitrary HFB multi-quasiparticle states
Qing-Li Hu, Zao-Chun Gao, Y. S. Chen
We present new formulae for the matrix elements of one-body and two-body physical operators in compact forms, which are applicable to arbitrary Hartree-Fock-Bogoliubov wave functio…
A convenient implementation of the overlap between arbitrary Hartree-Fock-Bogoliubov vacua for projection
Zao-Chun Gao, Qing-Li Hu, Y. S. Chen
Overlap between Hartree-Fock-Bogoliubov(HFB) vacua is very important in the beyond mean-field calculations. However, in the HFB transformation, the matrices are sometimes sin…
Can one identify the intrinsic structure of the yrast states in Cr after the backbending?
Zao-Chun Gao, Mihai Horoi, Y. S. Chen +2
The backbending phenomenon in Cr has been investigated using the recently developed Projected Configuration Interaction (PCI) method, in which the deformed intrinsic states…
Improved basis selection for the Projected Configuration Interaction method applied to heavy nuclei
