Elastic anomaly of heavy fermion systems in a crystalline field Running head: Elastic anomaly of heavy fermion systems

An elastic anomaly, observed in the heavy Fermi liquid state of Ce alloys (for example, CeCu6 and CeTe), is analyzed 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∆ is assumed between two energy levels. Fourfold degenerate conduction bands are also considered. We solve th...

Crystalline-Electric-Field Effect on the Resistivity of Ce-based Heavy Fermion Systems

The behavior of the resistivity of Ce-based heavy fermion systems is studied using a 1/N expansion method á la Nagoya, where N is the spin-orbital degeneracy of f-electrons. The 1/N -expansion is performed in terms of the auxiliary particles, and a strict requirement of the local constraints is fulfilled for each order of 1/N . The physical quantities can be calculated over the entire temperatu...

Theory of an elastic anomaly in the heavy fermion system CeTe

The elastic anomaly observed in the coherent Kondo state of Ce heavy fermion compounds is analyzed by using the Anderson lattice model simulating the energy level scheme of CeTe. The Γ7 doublets and Γ8 quartets of the 4f states are considered in the model. We solve the mean field equations to derive the temperature dependences of elastic constants, using the random phase approximation like expr...

Weyl–Kondo semimetal in heavy-fermion systems

Insulating states can be topologically nontrivial, a well-established notion that is exemplified by the quantum Hall effect and topological insulators. By contrast, topological metals have not been experimentally evidenced until recently. In systems with strong correlations, they have yet to be identified. Heavy-fermion semimetals are a prototype of strongly correlated systems and, given their ...
