Abstract:

Since its first discovery in 1979, heavy fermion superconductivity remains one of the big mysteries in condensed matter physics. The conventional theory fails to provide a satisfactory explanation to most heavy fermion properties. It is hence necessary to explore other routes to tackle this challenging problem. In this talk, after a brief introduction to the current status of heavy fermion research, I will discuss my recent work that revealed unexpected universal properties in the normal state of many heavy fermion materials, and propose a new framework that may eventually lead to a better basis for understanding heavy fermion superconductivity.
