Origins of High-Temperature Superconductivity in the New Copper Oxide Based Ceramic Superconductors: Foreign Trip Report, July 20, 1988-July 29, 1989.

摘要

The traveler spent a year at the University of Erlangen-Nuernberg, Erlangen, FRG, funded by a Senior US Scientist Award from the Alexander von Humboldt Foundation. Brief background information on the von Humboldt Foundation and on the Friedrich-Alexander- Universitaet Erlangen-Nuernberg is given. The traveler's theoretical work on high-T(sub c) superconductivity at Erlangen, carried out primarily at the Chair for Theoretical Chemistry, was concentrated on excitonic and spin-polaron mechanisms for superconductivity. Brief comments and observations related to interactions and travel during the year are given. Finally, some general observations about science and the university system in the Federal Republic of Germany are made.
