抄録

We study the pseudogap phenomena in the single-particle excitations in high-Tc cuprates, based on the mode-mode coupling theory of antiferromagnetic (AFM) and dx(2)-y(2)-wave superconducting (dSC) fluctuations. For the parameter values for underdoped cuprates, pseudogap structure develops in the single-particle excitations around (π, 0) and (0, π) points below the pseudo-spin-gap temperature TPG signaled by the reduction of low-energy spin correlations, while the calculated results for the overdoped cuprates show no clear pseudogap, in qualitative agreement with the experimental data.
