“Two-dimensional electrons: alive, well and kicking”
Abstract: Electrons in two dimensions, high magnet fields and at low temperature have shown very unusual properties, the weirdest of which being fractional electronic charge. While the initial discovery dates back more than two decades, research in this area has been flourishing ever since. This talk will try to give the uninitiated an intuitive interpretation of the different phenomena and try to give the initiated some examples of recent, puzzling results.
Short bio: Störmer received his Ph.D. in 1977 from the University of Stuttgart under Prof. Queisser and joined Bell Labs as a postdoctoral researcher in 1978. From 1983 to 1992 he headed the Semiconductor Physics Research Department and became the Director of the Physical Research Department of AT&T Bell Labs in 1992. In 1997 Störmer moved to the position of Adjunct Physics Director at Bell Labs and became a Professor in Physics and Applied Physics at Columbia University. He is one of the Scientific Directors of the Columbia NSF Nano Center. Störmer received numerous awards, including the 1998 Nobel Prize in Physics, which he shared with Dan Tsui (Princeton) and Robert Laughlin (Stanford) for the “discovery of a new form of quantum fluid with fractionally charged excitations.” Störmer is a member of several scientific organizations, including the National Academy of Science.
