Strongly Correlated Electron Behaviour in CeT2Al8(T = Fe, Co)

Strongly correlated electron systems.

Strongly correlated electron systems.

Electron-spin dynamics in strongly correlated metals.

The temperature dependence of the electron-spin lifetime T1 and the g factor are anomalous in alkali fullerides (K,Rb)3C60, which cannot be explained by the canonical Elliott-Yafet theory. These materials are archetypes of strongly correlated and narrow band metals. We introduce the concept of a "complex electron-spin resonance frequency shift" to treat these measurables in a unified manner wit...

Unified theory of strongly correlated electron systems

In framework of eigen-functional bosonization method, we introduce an imaginary phase field to uniquely represent electron correlation, and demonstrate that the Landau Fermi liquid theory and the Tomonaga-Luttinger liquid theory can be unified. It is very clear in this framework that the TomonagaLuttinger liquid behavior of one-dimensional interacting electron gases originates from their Fermi ...

Correlated-electron theory of strongly anisotropic metamagnets

Metamagnetic transitions in strongly anisotropic antiferromagnets are investigated within a quantum mechanical theory of correlated electrons. We employ the Hubbard model with staggered magnetization mst along an easy axis e in a magnetic field Hie. On the basis of the dynamical mean-field theory ~DMFT! this model is studied both analytically and numerically. At intermediate couplings the self-...
