报告题目:Materials, Energy and Life: Entertaining Aspects of High Magnetic Field Research
报告摘要:The MagLab exists to provide its international user community with unique magnets and expertise spanning condensed matter physics, materials research, chemistry, biochemistry, biology, and biomedicine. We generate magnetic fields exceeding two million times the Earth’s magnetic field. This talk seeks to answer the question, “Why would anyone want to do such a thing?” Illustrative examples from the portfolio of user research at the MagLab will include ? MATERIALS: tweaking macroscopic quantum phenomena in two-dimensional square lattices of copper and oxygen to achieve high-temperature superconductivity or magnetic Bose-Einstein condensation; ? ENERGY: analyzing nature’s most complex fluids, including petroleum, to improve utilization and mitigate pollution; and ? LIFE: tracking sodium and gadolinium quantum dots to revolutionize magnetic resonance imaging. During the talk, we anticipate that jokes will very likely be told.
The portion of the talk that surveys my own work on high-temperature superconductivity uses magnetic fields to suppress the superconductivity…with a goal of revealing the Wizard who pulls the strings behind the curtain. This work is a collaboration with Scott Riggs, Oskar Vafek and Jon Kemper of the MagLab branch at Florida State University; Jon Betts, Al Bert Migliori and Fedor Balakirev of the MagLab branch at Los Alamos National Laboratory; and W. N. Hardy, Ruixing Liang and Doug Bonn of the University of British Columbia.
