Polaronic Quasiparticles in a Strongly Correlated Electron Band

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...

Quasiparticles in a strongly correlated liquid with the fermion condensate : applications to high temperature superconductors

Quasiparticles in a strongly correlated liquid with the fermion condensate: applications to high temperature superconductors Abstract A model of a strongly correlated electron liquid based on the fermion condensation (FC) is extended to the consideration of high temperature superconductors. Within our model the appearance of FC presents a boundary, separating the region of strongly interacting ...

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 ...
