论文摘要
当前的工作研究电子相关性的方面,使用信息熵在其地面状态下的H $^{ - } $,He and Li $^+$原子。通过这种方式,使用不同的变异波函数,以更好地考虑库仑相关性。 $ s_r $,$ s_p $和$ s_t $熵获得的值对库仑相关效果很敏感。在强限制方案中,库仑相关性的效果可以忽略不计,并且使用独立粒子模型和两个不可穿透的球形笼子限制的非相互作用的电子在该方案中变得重要。最后,与文献中可用的结果相吻合,获得了能量值。
The present work studies aspects of the electronic correlation in confined H$^{-}$, He and Li$^+$ atoms in their ground states using the informational entropies. In this way, different variational wavefunctions are employed in order of better take account of Coulomb correlation. The obtained values for the $S_r$, $S_p$ and $S_t$ entropies are sensitive in relation to Coulomb correlation effects. In the strong confinement regime, the effects of the Coulomb correlation are negligible and the employment of the models of independent particle and two non-interacting electrons confined by a impenetrable spherical cage gains importance in this regime. Lastly, energy values are obtained in good agreement with the results available in the literature.
