报告摘要：It has been eight years since the discovery of the new families of Fe-based high-temperature superconductors. As more families discovered and more accurate experiments performed, richer and more interesting observations are added to the outstanding puzzle of high-temperature superconductivity. This talk will start by giving a general introduction of superconductivity and why it deserves serious attention, followed by an overview of the current findings in Fe-based superconductors. The last part of the talk will focus on the local electronic and orbital correlation that host of the superconductivity and strong quantum magnetic fluctuation observed in all the families.
