Horst L. Störmer, who won the 1998 Nobel prize in physics for his discovery of the fractional quantum Hall effect, delivered the concluding lecture at the Third Stig Lundqvist Conference on Advancing Frontiers of Condensed Matter Physics: Fundamental Interactions and Excitations in Confined Systems. His talk, which took place on 15 August, examined "Recent Results on Two-Dimensional Electrons." German-born Störmer, professor of physics at Columbia University, and part-time adjunct physics director at Bell Labs, Murray Hill, New Jersey, USA, is a leading specialist in the new and intriguing area of nanotechnologies.
