摘要
We calculate one-particle spectrum A(k, omega) in the presence of strong d-wave attractive inter action. We use the self-consistent T-matrix approximation and get anomalous behavior of the spectrum at low temperatures. The anomaly is characterized by a three-peak structure of the spectrum A(k = (pi, 0), omega). We also compare our result with that obtained hy the angle resolved photoemission spectroscopy and discuss the essential nature of the pseudogap.
