Abstract:
We examine the distribution of spectral weights (SWs) of the 2-dimensional t-t′-t″-J model describing cuprate superconductors in terms of the Gutzwiller projected Fermi liquid, as the possible normal state, and d-wave (superconducting) resonating valence bond state. Treat exactly strong correlation between electrons by numerical approach, we calculate SWs for removing an electron which can be compared with the observation made by the future angle-resolved photoemission spectroscopy experiment.
