Daniel C. Tsui coauthored the 1982 observation of a fractional quantum Hall effect. High-mobility electrons confined to two dimensions exhibited a Hall plateau with electrical resistance when the lowest spin-polarized Landau level was one-third filled. A simultaneous minimum in longitudinal electrical resistance distinguished a collective electronic state from an ordinary smooth change in transport. The result created a problem beyond the noninteracting integer Hall picture.[ref]

Daniel C. Tsui is a prominent physicist known for his significant contributions to the field of condensed matter physics. He was born on July 28, 1939, in Shanghai, China. Tsui is especially renowned for his work on the quantum Hall effect, a phenomenon observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields.
