Excited States beyond Mott Gap in Half-Filled-Band Hubbard Model
Hisatoshi Yokoyama, Kenji Kobayashi, Tsutomu Watanabe +1
In connection with recent experiments on excitation in which Mott insulators change to conductors, we study the properties of excited states beyond the Mott gap as quasi-stationary…

Crossover between BCS Superconductor and Doped Mott Insulator of d-wave Pairing State in Two-Dimensional Hubbard Model
Hisatoshi Yokoyama, Masao Ogata, Yukio Tanaka +2
With high-Tc cuprates in mind, properties of correlated dx2-y2-wave superconducting (SC) and antiferromagnetic (AF) states are studied for the Hubbard (t-t'-U) model on square latt…
