Abstract: In atomic systems, the Schrödinger equation for two electrons, for example the He-like atoms, could be solved approximately using the variational method incorporated with trial functions. Depend on the form of the trial functions, the eigenvalues could be calculated using the solution of the Schrödinger equation in spherical or Hylleraas coordinates. The solution gives the optimum wavefunctions, that one can used to calculate the information entropies (Shannon, Fisher, Rényi, Tsallis, etc.). The information entropy is a trigger for providing the information about the localization, extent, spread, shape and uncertainty of the electronic density distribution of states in r- or p- spaces. In this seminar, we will give an overview about our latest work regarding Rényi entropy for He-like atoms.

In atomic physics
It is known that entropy is a gauge for providing the information about the localization, extent, spread, shape and uncertainty of the electronic density distribution of states in the respective spaces.
