Robert B. Laughlin

Born 1 Nov 1950.American physicist whoshared(with Daniel C. Tsui and Horst Störmer) the Nobel Prize for Physics in 1998 for research on the fractional quantum Hall effect. In a current-carrying conductor, the classic Hall effect is the voltage produced at right angles to a magnetic field, as first discovered in 1879. A century later the German physicist Klaus von Klitzing discovered that in a powerful magnetic field at extremely low temperatures the Hall resistance of a semiconductor is quantized in integral “steps.” Using even stronger magnetic fields and lower temperatures, Störmer and Tsui discovered fractional steps, explained by Laughlin's theory that the electrons can form a new type of quantum fluid with quasiparticles carrying fractions of an electron's charge.
