Numerical Study of Pseudo-gap Anisotropy for a Tight Binding Band
L. Coffey
The Fermi surface anisotropy of a pseudo-gap in the spectral weight, caused by superconducting fluctuations or anti-ferromagnetic fluctuations, is calculated for a tight binding ba…
Superconducting Fluctuations in a Tight Binding Bandstructure
L. Coffey
Normal state superconducting fluctuations are calculated for the case of a tight binding bandstructure. The resulting electronic self energy and spectral weight are anisotropic on…
Calculation of Dip Features in the SIS Conductance of D-Wave Superconductors Using Eliashberg Formalism
L. Coffey
Recent SIS tunneling conductance measurements on a range of Bi2212 crystals with varying oxygen doping have revealed new information on the behavior of a dip feature in the tunneli…
Comment on Recent Tunneling Measurements on Bi-2212
Z. Yusof, L. Coffey
The asymmetry in the conductance peaks shown in recent PCT and STM measurements may be a signature of the d-wave gap. This is based on our model for the tunneling density of states…
