Bubble phase at for a spinless hollow-core interaction
Grégoire Misguich, Thierry Jolicoeur, Takahiro Mizusaki
We investigate fractional quantum Hall states for model interactions restricted to a repulsive hard-core. When the hard-core excludes relative angular momentum between spinle…

Gapless quantum spin liquid, stripe and antiferromagnetic phases in frustrated Hubbard models in two dimensions
Takahiro Mizusaki, Masatoshi Imada
Unique features of non-magnetic insulator phase are shown, and phase diagram for t-t' Hubbard model on square lattice is presented. Using the path-integral renormalization group me…

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…
