Four symposia are planned. Collective Phenomena Collective phenomena are an amplified manifestation of interactions between particles. Consequently their study as a function of pressure provides a fascinating and powerful probe into interparticle interactions of all kinds. In many instances kinetics and dynamics are involved, which adds to the fascination and complexity of the subject. The symposium Collective Phenomena at High Pressures will attempt to bring together the workers in this field for a coherent discussion of collective phenomena and the various dependencies - on pressure, primarily in a series of review papers interspersed with the latest experimental and theoretical results. Topics include charge density waves, ferroelectricity, magnetism and superconductivity. Contributions of oral and poster papers will be considered by the cochairmen, C.G. Homan and MacCrone. Write to: R.K. MacCrone Material Science Department Rensselaer Polytechnic Institute Troy, NY 12181 Electronic Transport Transport of charge and momentum in solids by electrons and holes obviously depends upon the freedom or binding of the electrons. The states and degree of binding that are possible depend upon the structure and the free volume available. Application of high pressure decreases the free volume available to the electron systems and changes the mobility - sometimes drastically, as in phase transitions. The purpose of the symposium, Electronic Transport Phenomena in Solids at High Pressure, is to bring together experimental and theoretical workers in this field to present, discuss and correlate relatively recent observations and developments with the aim of a better understanding of the behavior of matter over a wide range of
density. The subject area will be limited to solid specimens under static or dynamic pressure at temperatures ranging from high to low, and possibly subject to superimposed conditions such as electric, magnetic or sonic fields, or to theoretical considerations applying to such conditions. Invited speakers include K.-J. Dunn, University of California, Los Angeles; J. Schirber, Sandia National Laboratories; S. Minomura, University of Tokyo; R. Clarke, University of Michigan; B. Sundqvist, University of Umea, Sweden; and E. Iskevitch, Institute of High Pressure Physics, Moscow. The program is being organized by co-chairmen F.P. Bundy and B.A. Lombos. Contributed papers should be submitted to: F.P. Bundy General Electric Research & Development Center P.O. Box 8 Schenectady, NY 12301 Fluids The study of fluids under high pressure greatly helps a fundamental understanding of the behavior of matter, and of many technical processes in shock waves, thermonuclear fusion, geophysics and geochemistry, planetary and stellar science, and other fields. This study has made great progress in recent years in the magnitude of the pressure and temperature ranges, in the scope and accuracy of measurements, and in the theory. The Fluids Under High Pressure symposium is intended to bring together workers in all these fields to e
