| Conductivity, Superconductivity and the Quantum World | ||

| The conduction of electricity through a wire is part of our common everyday experience and seems easy to understand. Yet we now know of many examples where the quantum (wave-like) nature of the electron shows up in a simple conductivity measurement. Professor Lee will describe in his lecture a few of these examples, such as the quantized conductance steps through a constriction and the phenomenon of universal conductance fluctuations. The ultimate manifestation of the quantum world is the phenomenon of superconductivity, where current is carried with exactly zero resistance. He will also argue that the exactness has to do with topology. | ||
