摘要：
We calculate the one-hole spectral function for the polarized t-J model using exact diagonalization for a finite size cluster. A well-defined quasiparticle peak appears at the bottom of the spectrum for intermediate values of J. The momentum of the quasiparticle corresponding to the bottom of the band varies with the magnetization and the strength of the coupling J. We use these results to analyze the one-particle spectra in strong coupling superconductors.
