journal contribution
posted on 2010-01-22, 16:43 authored by A.S. Alexandrov, Joanne BeanlandWe develop a theory of normal metal–superconductor and superconductor tunneling in “bosonic” superconductors with strong attractive correlations taking into account coherence effects in single-particle excitation spectrum and disorder. The theory accounts for the existence of two energy scales, their temperature and doping dependencies, asymmetry, and inhomogeneity of tunneling spectra of underdoped cuprate superconductors.
