抜粋

Pseudogap phenomena in high-Tc. cuprates are examined. The effective action for 2D electron systems with antiferromagnetic (AFM) and dx2-y2-wave superconducting (dSC) fluctuations is considered. By the SCR (self-consistent renormalization), the spin and the pairing correlation lengths, ξσand ξd, and 1/T1 T are calculated. The pseudogap (PG) emerges when dSC short-range order (SRO) dominates over AFM-SRO. When damping for the spin wave strongly depends on ξd through the formation of precursor singlets around (π, 0) and (0, π) points, the spin PG in underdoped cuprates is reproduced. Otherwise, the PG region shrinks as in overdoped cuprates.
