| Abstract |
|
|
|
| In the context of quantum information, both Shannon entropy and the different Jaynes entropy for a two-electron "entangled artificial" atom proposed by Moshinsky are studied here. The Jaynes entropy in this model is shown to be intimately related to the correlation kinetic energy. A generalization of the customary Shannon entropy based on the electron density is then proposed in terms of the electron pair correlation function. Both definitions behave in a similar way to the Jaynes entropy when considered as a function of the strength of the model electron-electron interaction. | |
