Interplay between Electron Correlations and Quantum Orders in the Hubbard Model

Interplay between Electron Correlations and Quantum Orders in the Hubbard Model

Show other versions (1)

We discuss the appearance of quantum orders in the Hubbard model for interacting electrons, at half-filling. Such phases do not have local order parameters and need to be characterized by the quantum mechanical properties of their ground state. On one hand, we study the Mott transition from a metal...
