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…
