, of the 1998 Nobel Prize in Physics. 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. Tsui and Störmer observed the phenomenon, which is now known as the fractional quantum Hall effect, in their laboratory in 1982, and Laughlin later provided the theoretical explanation for it.
