Synchrotron Radiation Spectroscopy on Strongly Correlated Electron Systems

Solids with strong electron–electron interaction, namely strongly correlated electron systems (SCES), have various physical properties, such as non-BCS superconducting, colossal magneto-resistance, heavy fermion and so on, which cannot be predicted by first-principle band structure calculation. Due to the physical properties, the materials are the candidates of the next generation functional ma...

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 ...

Quantum Simulations of Strongly Correlated Electron Systems

We review recent progress in developing new quantum Monte Carlo methods for simulating strongly correlated electron systems. We then present a summary of our ongoing studies of the Hubbard model with these methods, including the ground-state constrained path Monte Carlo method and a new nite-temperature method. These methods make possible simulations at large system sizes and low temperatures. ...
