An overview of the historic and current developments in superconductivity will be be presented. The phenomenon of superconductivity was discovered almost 100 hundred years ago and it is still one of the hottest research topics providing fascinating puzzles and challenges to both theoreticians and experimentalists. There was a lag of almost 50 years between the experimental discovery of (low...

In this talk, I will provide a perspective on the fundamental properties of the cuprate high-temperature superconductors (HTS), and how early and ongoing fundamental research has identified the strengths and weaknesses, and has ultimately led to the development of superconducting wires for power applications--the so-called "coated conductors." Early work on the properties of various classes of...

Since its discovery 100 years ago, superconductivity has captured the imagination of many as a fascinating physical phenomenon which would enable the drastic reduction of energy waste in the electric power grid, high field magnets and large accelerators. Understanding the physics of superconductivity has been advancing along with the discovery of many superconducting materials and tuning their...

In this Talk, I describe the most recent progress in the field of iron-based superconductors. Using neutron scattering as a probe, we study the spin wave excitations in BaFe2As2 and RbFe1.6Se2, and its electron/hole doping evolution of the spin excitations. We find that the effective next nearest neighbor (NNN) exchange interactions for different families of materials are rather similar, thus...
