Advanced Concepts of Superconductivity: A Comparative Review of Soviet and American Research. Part I, High-Temperature Superconductivity.
A comprehensive and comparative review of U.S. and Soviet advances in high-temperature superconductivity (HTS) theory and experiments through September 1973. A discussion of the basic concepts of the Ginzburg-Landau and BCS theories is followed by more controversial advanced concepts of HTS, which include exciton processes on one- and two-dimensional structures. Recent results in TCNQ complexes, and arguments which dispute them, are explored. The report stresses a possibility of a major increase in the critical temperature having pervasive effects on electrical technology. HTS research lagged badly in the United States during the sixties but is now approximately on par with Soviet. The USSR has a high degree of capability and preparedness in this field due to coherent funding and organization, stable research staff population, interdisciplinary approach. Soviet research style is not generally conducive to rapid exploitation of results. 83 pp. Ref.
