主讲人/SpeakerDung-Hai Lee, Ph.D., Professor of Physics, University of California, Berkeley, USA


Professor Dung-Hai Lee received his B.S. degree from the Tsinghua University of Taiwan. He went to the Massachusetts Institute of Technology in 1977 for graduate study and received his Ph.D. in physics in 1982. After staying at M.I.T. for another two years, he joined the IBM T.J. Watson Research Center in 1984. Professor Lee spent eleven years at IBM, and came to Berkeley in February 1994. Professor Lee is a theoretical condensed matter physicist. The principal goal of his research is to develop the theory for topological phase transitions and to understand the mechanism of high-temperature superconductivity. More generally he is interested in new organization principles enabling microscopic degrees of freedom to behave cooperatively in a fundamentally new manner. His research is in the arena of strong-correlated many-body physics.


报告题目/Title:

High-Temperature Superconductivity


讲座摘要/Abstract:

Raising the superconducting transition temperature to a point where applications are practical is one of the most important challenges in science. In 1986 a family of superconducting materials, namely the copper-oxide superconductors, was discovered. To date, the highest transition temperature is ~140K. However, despite unprecedented research efforts, the precise cause of the high transition temperature is still controversial. In 2012 a new interface high-temperature superconducting system was discovered. This system is based on entirely different materials. However, it shares many common features with the copper-oxide superconductors. Moreover, the reason underlies its high transition temperature has been found in the last few years. In this talk, I shall explain the mechanism for strong Cooper pairing in this system and what it teaches us about finding even higher temperature superconductors.
