Nonequilibrium Quantum Breakdown in a Strongly Correlated Electron System

During the past decades, there has been an increasing fascination and surprises with diverse quantum many-body effects. With the magical touch of interaction a simple electron system may assume insulating, metallic, magnetic or superconducting states according as the control parameters are changed. Strongly correlated electron systems, as exemplified by the high-Tc superconductors and their hos...

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 ...
