Polaronic effect in lightly doped high-Tc cuprates

Sakai, Toru; Poilblanc, D.*

The effect of in-plane oxygen phonons is investigated by numerical exact diagonalizations of the t-J Holstein model. The present study indicates that the breathing vibration mode gives rise to a polaronic effect which yields a broadening of the single hole quasiparticle spectrum and a shift from the chemical potential, as the one observed in angle-resolved photoemission spectroscopy.
