Nanoscale Coherence Near Defects: Superconductivity, Spin Ordering, and Their Coexistence

Abstract

This is a report of progress in theoretical calculations of the influence of impurities on tunneling spectroscopy in high-temperature superconductors. The calculations have been improved by the addition of energy-dependent linewidths and bilayer splitting. Notable results include the use of Ni as a local probe for superconductivity, the lack of splitting from the bilayer of the quasiparticle resonances, and the independence of low-energy quasiparticles from bilayer splitting. Preliminary theoretical views of noise in tunnel junctions have been presented as well.
