The Cooperon and the Random Matrix Model for Type-II Superconductors
Safi R. Bahcall
We derive the connection between the Cooperon problem in weak localization theory and the random matrix description of type-II superconductors. As magnetic field and disorder incre…
C-axis Josephson Tunneling Between YBCO and Pb: Direct Evidence for Mixed Order Parameter Symmetry in a High-T_c Superconductor
K. A. Kouznetsov, A. G. Sun, B. Chen +10
We report a new class of -axis Josephson tunneling experiments in which a conventional superconductor (Pb) is deposited across a single twin boundary of a YBa_2Cu_3O_{7-δ} cryst…
Non-perturbative Effects Near the Upper Critical Field in Type-II Superconductors
Safi R. Bahcall
The properties of a conventional type-II superconductor near the upper critical field are usually calculated using a perturbative expansion in the strength of the order parameter.…
Boundary Effects and the Order Parameter Symmetry in High-Tc Superconductors
Safi R. Bahcall
Apparently conflicting phase-sensitive measurements of the order parameter symmetry in the high-T superconductors may be explained by regions near surfaces in which the order p…
