CHIGO-ANOTA, Ernesto  and  RIVAS SILVA, Juan Francisco. Correlación electrónica fuerte: sistemas con electrones 4f y 5f. Rev. Soc. Quím. Méx [online]. 2003, vol.47, n.3, pp.221-226. ISSN 0583-7693.

We try to explain the strong electronic correlation (SEC) concept which is presented in solid materials such as superconductors at high T_c and the heavy fermion (HF) systems that contain Ce ions with 4f electrons and U or Np ions with 5f electrons and transition metals compounds. The effect has been matter of study in modern and complex new theories by certain groups of researchers they are not easily applied to computational program.

Keywords : Strong electronic correlation; heavy fermions.
