Title: "Fractional Charges and other Tales from Flatland"
Abstract:
Two-dimensional electrons in a semiconductor reveal
to us totally new many-particle physics. Confined to a plane and
exposed to a magnetic field such electrons display an enormously
diverse spectrum of fascinating new properties. Fractional charge and
fractional quantum numbers are probably the most spectacular
consequences of such correlated electron behavior, but there are many
other surprises. They are just electrons -- although lots of
them.
