Abstract
This is a report on the progress in theoretical calculations of scanning tunneling microscopy spectra near impurities in superconductors. Calculations have been performed for Zn and Ni impurities in BSCCO, and compared with recent scanning tunneling microscopy spectra near those impurities. Good quantitative agreement has been found. The Zn atom appears to locally destroy superconductivity. New experiments involving two Ni atoms and a Ni and Zn atom have been proposed to clarify the range of this effect from Zn, and also to observe the spin-spin correlation function in the superconducting state.
