Multipole nuclear shielding factors of hydrogen atom confined by a spherical cavity
Yu Qing Dai, Zhi Ling Zhou, Henry E. Montgomery +3
Nuclear shielding factor is an important quantity to describe the response of an atom under the perturbation of an external field. In this work, we develop the sum-over-states nume…
Finite-nuclear-size effect in hydrogen-like ions with relativistic nuclear structure
Hui Hui Xie, Jian Li, Li Guang Jiao +1
The finite-nuclear-size (FNS) effect has a large contribution to the atomic spectral properties especially for heavy nuclei. By adopting the microscopic nuclear charge density dist…
Critical nuclear charge and shape resonances for the two-electron systems
Zong-Chao Yan, Yew Kam Ho
The hydrogen negative ion H is the simplest two-electron system that exists in nature. This system is not only important in astrophysics but it also serves as an ideal ground t…
Quantification of entanglement entropy in helium by the Schmidt-Slater decomposition method
Chien-Hao Lin, Yew Kam Ho
In this work, we present an investigation on the spatial entanglement entropies in the helium atom by using highly correlated Hylleraas functions to represent the S-wave states. Si…
Quantum entanglement for two electrons in the excited states of helium-like systems
Yen-Chang Lin, Yew Kam Ho
The quantum entanglement for the two electrons in the excited states of the helium-like atom/ions is investigated using the two-electron wave functions constructed by the B-spline…
Quantification of linear entropy for quantum entanglement in He, H- and Ps- ions using highly-correlated Hylleraas functions
Chien-Hao Lin, Yen-Chang Lin, Yew Kam Ho
The quantum entanglement for the two electrons in three-body atomic systems such as the helium atom, the hydrogen negative ion and the positronium negative ion are investigated by…
