Annual rept. for Contract AFOSR-91-0337 (Southern University)
Abstract
The year of 1992-1993 is a highly-productive year for the project of the Computer Simulation Study of High Temperature Superconductor Structure. In this year, the main barrier to the simulation was overcome. A pai-interaction potential between a pair of charges such as electron-electron, hole-hole, and electron-ion, etc. in a layered two dimensional system was obtained. It amazingly presents negative values within a certain interparticle distances that should have been absolutely positive according to the Coulumb's law. Of most importance is that while discovering this, the essence of high temperature superconductivity was probably touched. It was shown that quite a lot of anomalous behaviors of high temperature superconductors can be explained and understood by means of this interaction potential. The mysterious phase transition from an insulator to a superconductor is well understood and the transition temperature is calculated showing consistency with measurements.... High temperature superconductivity.
