Quantum-number projection in the path-integral renormalization group method
Takahiro Mizusaki, Masatoshi Imada
We present a quantum-number projection technique which enables us to exactly treat spin, momentum and other symmetries embedded in the Hubbard model. By combining this projection t…

New Type of Degenerate Quantum Spin Phase
Masatoshi Imada, Takahiro Mizusaki, Shinji Watanabe
Correlated electrons often crystalize to the Mott insulator usually with some magnetic orders, whereas the "quantum spin liquid" has been a long-sought issue. We report numerical e…
