A selection of papers by theoretical physicist and Nobel laureate J. Robert Schrieffer. In addition to his Nobel Prize-winning work in superconductivity, Professor Schrieffer has made significant contributions to a wide variety of topics in condensed matter physics. These include the theory of soliton excitations in polyacetylene (a clear example of spin-charge separation in a condensed matter system), paramagnon theory, magnetic impurities, the physics of surfaces, high-Tc superconductivity, and the fractional quantum Hall effect. The papers are reviewed and placed in context by experts. The guest contributors are A. Alexandrov, T. Einstein, S. Kivelson, D. Scalapino, F. Wilczek, J.W. Wilkins and S.C. Zhang.
