Fisher information for endohedrally confined hydrogen atom

Publication date: Available online 3 October 2019Source: Physics Letters AAuthor(s): Liangyong Wu, Shengqi Zhang, Bowen LiAbstractElectron localization and delocalization of endehedrally confined hydrogen atom has been investigated employing Fisher information theory. Confinement has been modeled using a spherical Gaussian-type potential. B-spline bases expansion method was used to solve the Schrödinger equation to obtain the required energy eigenvalues and the corresponding wave functions. Changes in energies with depths of potential are explained using Hellmann-Feynman theorem. The behavior of Fisher information against the confining potential depths and positions are demonstrated. Moreover, our results show that Fisher information is an effective way to measure the localization of valence electrons.
