Universality Classes of Metal-Insulator Transitions in Strongly Correlated Electron Systems and Mechanism of High-Temperature Superconductivity
Masatoshi Imada
We study three regimes of the Mott transitions characterized by classical, marginally quantum and quantum. In the classical regime, the quantum degeneracy temperature is lower than…
Charge Ordered Insulator without Magnetic Order Studied by Correlator Projection Method
Kota Hanasaki, Masatoshi Imada
The Hubbard model with additional intersite interaction `' (the extended Hubbard model) is investigated by the correlator projection method (CPM). CPM is a newly developed numer…
Electronic Structure of Strongly Correlated Systems Emerging from Combining Path-Integral Renormalization Group with Density Functional Approach
Yoshiki Imai, Igor V. Solovyev, Masatoshi Imada
A new scheme of first-principles computation for strongly correlated electron systems is proposed. This scheme starts from the local-density approximation (LDA) at high-energy band…
Thermodynamic Relations in Correlated Systems
Shinji Watanabe, Masatoshi Imada
Several useful thermodynamic relations are derived for metal-insulator transitions, as generalizations of the Clausius-Clapeyron and Eherenfest theorems. These relations hold in an…
Quantum Mott Transition and Superconductivity
Masatoshi Imada
The gas-liquid transition is a first-order transition terminating at a finite-temperature critical point with diverging density fluctuations. Mott transition, a metal-insulator tra…
Quantum Mott Transition and Multi-Furcating Criticality
Masatoshi Imada
Phenomenological theory of the Mott transition is presented. When the critical temperature of the Mott transition is much higher than the quantum degeneracy temperature, the transi…
