The program and 24 abstracts are given. The abstracts are divided into the following categories: structure and elastic properties, transport and electronic properties, magnetism and superconductivity, and phonons. The engineering of novel materials using sophisticated preparation techniques has received considerable attention in recent years. This interest has been mainly stimulated by recent developments in preparation techniques such as Molecular Beam Epitaxy, Thermal Vapor Deposition and Sputtering. These advances in deposition technology allow for the first time the preparation of layered materials with well defined layer thicknesses approaching interatomic spacing and opens up new avenues for the production and stabilization of materials that do not occur in nature. In addition to the extensive experimental work on artificial semiconductor superlattices there has been a parallel, almost independent, development relating to artificial metallic superlattices. Although the experimental sophistication of the field is considerable the development of major related theoretical ideas has not kept pace. In view of the large body of experimental work, a pressing need exists for the development of conceptual ideas relating to the novel physics that is created by artificially adding a new periodicity to the lattice. Because of this the Office of Naval Research is sponsoring the first "Workshop …
