Störmer, Horst Ludwig, 1949–, German physicist, Ph.D. Univ. of Stuttgart, 1977. He joined the research staff at Bell Labs in Murray Hill, N.J., in 1978. Störmer and Daniel Tsui were co-recipients, with Robert Laughlin, of the Nobel Prize in Physics in 1998. They discovered that electrons acting together in strong magnetic fields can form new types of quasiparticles that have just a fraction of the electrical charge an electron is supposed to have. Störmer and Tsui observed the phenomenon, which is now known as the fractional quantum Hall effect, in their laboratory in 1982, and Laughlin later explained their observations.
