Nano*High: Superconductivity, Trains and SQUIDs
Category
Published on
Abstract
Superconductivity is a unique phenomenon where the electric resistance of a material drops to zero. Until only a few decades ago, superconductivity was only observed at extremely low temperatures. Today however, a new class of exotic high-temperature superconducting materials is making possible powerful new loss-less electronics, now used in such devices as medical scanners, mag-lev trains, and the Large Hadron Collider. New research has also applied properties of superconductivity to develop the most sensitive detector ever made, the SQUID device.
Bio
John Clarke received his B.A. (1964), Ph.D. (1968), and Sc.D. (2005) from Cambridge University. After a postdoctoral fellowship at UC Berkeley, he joined the Physics faculty in 1969. He received the Distinguished Teaching Award in 1983. He is a fellow of the Royal Society of London, the American Physical Society, the American Association for the Advancement of Science, and the Institute of Physics (UK). He has been a Sloan Foundation Fellow, a Guggenheim Fellow and a Miller Professor. In 1987, he was named California Scientist of the Year and was awarded the Fritz London Prize for research in low-temperature physics. In 1998, he received the American Physical Society’s Joseph F. Keithley Award for Advances in Measurement Science and, in 1999, the National Academy of Sciences’ Comstock Prize for Physics. He was awarded the Hughes Medal of the Royal Society in 2004, and was the UC Berkeley Faculty Research Lecturer in 2005.
