Fractional Exclusion Statistics for the t-J Model
Yusuke Kato, Yoshio Kuramoto
We construct thermodynamics of the one-dimensional supersymmetric {\it t-J} model with the interaction and hopping. The thermodynamics is described exactly in terms of…

Variational Monte Carlo Studies of t-J-type Models
Hisatoshi Yokoyama, Yoshio Kuramoto, Masao Ogata
We give a brief review of recent developments by the variational Monte Carlo method, in addition to some new results. We discuss --type models: the ordinary - model in…

Exact Results for Spin and Charge Dynamics of Electrons with Supersymmetry
Y. Kuramoto
Excitation spectra in the SU(,1) supersymmetric t-J model with long-range exchange and transfer has quadratic dependence on spin and charge currents for all energies. After br…
