 Why Cuprate Superconductors are So Difficult to Understand

-- Learning from Transport Properties --

Abstract:  Already two decades have passed since the high-Tc superconductivity was discovered in cuprates, but its mechanism remains one of the biggest unsolved problems in the contemporary physics. The difficulty lies in the lack of fundamental understanding of the electronic structure of cuprates, which concerns the physics of “doped Mott insulator” where strong electron correlations preclude conventional theoretical approach. In this talk, I will illustrate how the transport properties of cuprates starkly demonstrate the unconventional electronic nature, and discuss the essential ingredients for its understanding inferred from our experiments.
