The 33rd annual Sanibel Symposium, organized by the faculty and staff of the Quantum Theory Project of the University of Florida, was held March 13 to 20, 1993, at the Ponce de Leon Conference Center located at the north gate of the city of St. Augustine, Florida. The topics of the sessions covered by these proceedings include Advanced Scientific Computing, Interaction of Photons and Matter, Quantum Molecular Dynamics, Electronic Structure Methods, Polymeric Systems, and Quantum Chemical Methods for Extended Systems.

One of the breakthroughs in condensed matter physics is the newly acquired ability of theorists to explain and predict properties of solids using quantum theory. Starting with minimal information about the constituent atoms, accurate calculations of electronic, structural, vibrational, and even superconducting properties of solids have been performed. The discussion will provide an overview of this area with emphasis on the predictive capacity of the approach. Applications include the analysis of high pressure structures of solids such as group IV and III-IV semiconductors, metallic hydrogen, and compounds having very low compressibilities. A pseudopotential approach is used in most of the above applications. In some cases empirical theories and scaling laws are employed as a guide to facilitate the investigation of trends in material properties. Specific compounds are suggested as candidates for superhard materials and new superconductors. Keywords: Military publications; Periodicals; Scientific literature; Reports; Europe; Translations.

The 34th annual Sanibel Symposium, organized by the faculty and staff of the Quantum Theory Project of the University of Florida, was held on February 12- 19, 1994 at the Marriott at Sawgrass Resort, Ponte Vedra Beach, Florida. More than 300 participants gathered for 8 days of lectures and informal discussions. The format of the symposium adopted for the past few years was followed again this year with a compact 8-day schedule with an integrated program of quantum biology, quantum chemistry, and condensed matter physics. The topics of the sessions covered by these proceedings include Propagator and Resolvent Theory, Perturbation Theory, Density Functional Theory for Molecules, High Performance Parallel Computing Algorithms, Weakly Bound Molecular Systems, Theoretical Inorganic Chemistry, Temporal Phenomena, Quantum Dynamics at Interphases, Energy Depositions, Non-Linear Optical Phenomena, and Novel Condensed Systems. The articles have been subjected to the ordinary refereeing procedures of the International Journal of Quantum Chemistry. (jg)

The 32nd annual Sanibel Symposium was held March 14 to 21, 1992. The format of the symposium adopted for the past 2 years was followed again this year providing a compact 8-day schedule with an integrated program of quantum biology, quantum chemistry, and condensed matter physics. The topics of the sessions covered by these proceedings include Thirty-five Years of Progress in Electronic Structure Theory, Density Matrices and Other Revelations of 1955, Non-Born-Oppenheimer Methods, Atomic and Molecular Phenomena in Astrophysics, Photoinduced Phenomena, Reactive Molecular Collisions, Quantum Monte Carlo, Density-Functional Theory, Thin Films and Surfaces. A special session on Theoretical Inorganic Chemistry was held in memory of Arnold Karo, one of the real old-timers at Sanibel. All the articles have been subjected to the ordinary refereeing procedures of the The International Journal of Quantum Chemistry. The articles presented in the sessions on quantum biology and associated poster sessions are published in a separate volume of the The International Journal of Quantum Chemistry....
