Strongly Correlated Cerium Systems: Non-Kondo Mechanism for Moment Collapse [PDF]

, 2000
We present an ab initio based method which gives clear insight into the interplay between the hybridization, the coulomb exchange, and the crystal-field interactions, as the degree of 4f localization is varied across a series of strongly correlated ...
