Exact Diagonalization Study of Strongly Correlated Electron Models: Hole pockets and shadow bands in the doped t-J model
Y. Ohta, R. Eder
A detailed exact-diagonalization study is made for the doping dependence of the single-particle spectral function and momentum distribution function of…

Spin dynamics of the doped t-J model
R. Eder, Y. Ohta
We present a new method for studying the low energy excitations in finite cluster systems and apply it to clarify the nature of the low energy spin excitations in the moderately do…
