Dynamical Processes and Ordering on Solid Surfaces

This volume is the proceedings of the Seventh Taniguchi International Sympo­ sium on the Theory of Condensed Matter. The symposium was held for five days from September 10 to 14, 1984 at Kashikojima, Mie, Japan. Dynamical proces­ ses and ordering on solid surfaces are the subjects of the symposium. About twenty participants stayed together at Shima Kanko Hotel, the symposium site, during the period. The intense and productive discussion in the bright sea­ s ide atmosphere of Kashi koj ima is bel i eved to have been impress i ve to all the participants. Dynamical processes on solid surfaces are the target of recent theoreti­ cal efforts in surface physics. Even if some of them are still in their in­ fant stage, important aspects begin to appear and vital concepts start to shape themselves. Some topics in the symposium were the energy transfer re­ lated with internal degrees of freedom of molecules, attempts to go beyond the trajectory approximati on, charge transfer and energy transfer between particles and solid surfaces, and related fundamental problems like adiaba­ tic potentials and electronic structures. In particular, really actively di scussed was the time-dependent Newns-Anderson model wi thout and wi th the intraatomic Coulomb interaction and sometimes with the interaction to the surface plasmons or phonons. Surface effects on the optical processes were discussed with great interest, such as the ABC-related problems of exciton polaritons and rare gas adsorbates on metal surfaces.
