Myth and Reality in High-Tc Superconductivity

Abstract

I will discuss two major themes. First I will discuss various experimental developments which seriously restrict the possible theoretical alternatives, such as the electron-based material (NdCe)2CuO4, the low spin susceptibility which shows that the magnitude of the specific heat jump is anomalous, the large gap-like structures at ~ 500 cm−1 observed in photoemission and the infrared, the evidence for small coherence lengths, etc. Second I will discuss some modern trends in the theory of the one-band Hubbard model which is the appropriate theoretical framework for high Tc: separation of charge and spin due to twisted order parameter in the Néel ordered state near half-filling, the topological renormalization due to doping which leads to generalized flux phases, and possible superconducting order parameters in generalized flux phase states.
