# Elastic anomaly of heavy fermion systems in a crystalline field

@article{Harigaya1993ElasticAO, title={Elastic anomaly of heavy fermion systems in a crystalline field}, author={Kikuo Harigaya and Gillian A. Gehring}, journal={Journal of Physics: Condensed Matter}, year={1993}, volume={5}, pages={5277-5282} }

An elastic anomaly, observed in the heavy Fermi liquid state of Ce alloys (for example, CeCu6 and CeTe), is analysed by using the infinite-U Anderson lattice model. Four atomic energy levels are assumed for f-electrons. Two of them are mutually degenerate. A small crystalline splitting 2 Delta is assumed between two energy levels. The fourfold degenerate conduction bands are also considered in the model. The authors solve the model using the mean-field approximation to slave bosons, changing…
