Saturday Physics for Everyone
The amazing sight of superfluid helium dripping through a solid container and of a magnet floating peacefully above a superconductor are macroscopic manifestations of essentially quantum phenomena. While we understand many aspects of these exotic phenomena, important questions, such as the microscopic mechanism of high-temperature superconductivity, still remain unanswered. Not only will solving these puzzles enrich our understanding of fundamental physics, it will also lead to tremendous advances in decreasing our energy consumption, which in turn will have a direct impact on greenhouse emissions. But how do we obtain the necessary microscopic information on the quantum properties of electrons in solids? A critical component to this is the ability to directly "see" the behavior of matter on the scale of atoms and electrons. In this talk, I will describe the miracle of the modern scanning tunneling microscope, which actually uses quantum mechanics for its basic operation. I will describe how we can use this quantum microscope to probe and manipulate atoms and electrons and how this powerful tool can be used to obtain microscopic quantum information on many materials, including high-temperature superconductors.
