SUMMARY OF RESEARCH

The research efforts I have made are focused on the mechanism of high-temperature superconductivity (HTSC): simulational and analytical.

The starting point of my thrust in superconductivity is the molecular-dynamics simulation study of the structure of high- temperature superconductors (HTS's), funded by AFOSR from July 1, 1991 to Dec. 1994. One year later I switched my major attention to microscopic analytical study based on the Landau Fermi liquid theory and many-body theory.

I am currently involved in both analytical and simulational investigations. The speed in simulation is slowed down due to the lack of manpower and computational ability at Southern University. The supercomputer Cray Y-ND provided for my project in NCSA at UIUC has retired. A new account of a more powerful supercomputer is being applied and a leaning is also needed.

Currently, my research is supported by DOE through a joint project with three other Historically Black Colleges and Universities. A plan of research expansion:

• A. Superconducting materials
  1. Theory (analytical and simulational):
     • (a)mechanism of HTSC,
     • (b)unification of conventional and high-Tc superconductivity,
     • (c)applied theory of HTS's such as impurity-doping theory, magnetic flux
     dynamics of HTSC in the wire form due to the mechanical stress, interfacial effects and se phase precipitates, etc.,;

     These are and will be performed in the current efforts and proposed projects (pending) and a part of them can be performed in the project cooperated with TCSUH.

  2. Experiment
     • (a) high-pressure induced phase transition of cuprates,
     • (b) superconductor-insulator device design

     These will be done in the cooperative project with C. W. Chu at TCSUH and will propose to do it at Southern University Baton Rouge, LA (SUBR);
