Physics Colloquium - Quantum Materials: from superconductors to insulators... and back!

Description:
The discovery of high-temperature superconductivity in iron-based pnictide compounds has sparked a flurry of activity in the condensed matter physics community and reinvigorated the hopes of discovering higher-Tc materials. Nearly in parallel, a new class of materials, the topological insulators, have also caught the attention of the world with promises of demonstrating exotic physical phenomena and new spin-based technologies. Representing two fundamentally different classifications of states of matter, these two fields of research have quickly intermingled and together hold promise for realizing new physics, including a long sought exotic fundamental particle called the Majorana fermion. In this talk Professor Johnpierre Paglione will introduce the important aspects of the new iron-based superconductors and review our recent finding of a 49 K intermetallic superconductor. {Will appear in FYI on Sep 18, 2012
