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. ...

Cluster methods for strongly correlated electron systems

The development of dynamical mean field methods has resulted in significant advances in our understanding of strongly correlated electron systems, in particular in the area of the Mott transition. This method captures the local effects of correlations such as the Kondo effect and the transfer of spectral weight between the coherent and the incoherent part of the spectral function. It suffers, h...
