Two-electron resonances in quasi-one dimensional quantum dots with Gaussian confinement
Arkadiusz Kuroś, Anna Okopińska
We consider a quasi one-dimensional quantum dot composed of two Coulombically interacting electrons confined in a Gaussian trap. Apart from bound states, the system exhibits resona…

Entanglement entropies in the ground states of helium-like atoms
Przemyslaw Koscik, Anna Okopinska
We examine the entanglement in the ground states of helium and helium-like ions using an original Hylleraas expansion. The von Neumann and linear entropies of the reduced density m…
