Under his previous award, Dr. Laughlin helped establish the                     correctness of the theory of the fractional quantum hall effect                 as it is presently understood and began the search for other                    examples of this behavior, particularly in certain classes of                   magnets thought to be relevant to high temperature                              superconductivity.  He made a case that the "resonating valence                 bond" state of Anderson, insofar as it is realized in real                      systems, is really the fractional quantum hall state in                         disguise, and that the long-range gauge force between                           quasiparticles, known in the quantum hall literature as                         "fractional statistics," is the root cause of superconductivity                 in these materials.  He will continue this search with particular               emphasis on the superconductor problem and on finding examples of               the behavior in three dimensions.
