Advanced Concepts of Superconductivity: A Comparative Review of Soviet and American Research. Part I. High Temperature Superconductivity
Abstract
This report reviews novel mechanisms for achieving high temperature superconductivity (HTS), the most promising of which is the exciton process. Section I summarizes the HTS research programs in the United States and in the USSR, from the publication of the Bardeen-Cooper-Schrieffer theory (1957) in the United States and the Ginzburg-Landau theory (1950) in the USSR, and ending with the present. The introduction also cites examples of known superconductors and their critical temperatures, and it briefly discusses the conventional applications of superconductivity. Comments are made on the tradeoff between cryogenic devices and potential HTS variants. Cautious optimism is expressed toward work on excitonic superconductors currently under way in both countries. HTS technical material is reviewed in Sections II and III, which lay groundwork for the assessment of the American and Soviet efforts in the concluding Section IV.
