Conductance characteristics between a normal metal and a clean superconductor carrying a supercurrent
(American Physical Society, 2004)The effect of a transverse supercurrent I-s up to the thermodynamic critical current on the low-temperature conductance characteristics between a normal metal N and a clean s- or d-wave superconductor (S) is theoretically ... -
Conductance characteristics between a normal metal and a two-dimensional Fulde-Ferrell-Larkin-Ovchinnikov superconductor: The Fulde-Ferrell state
(American Physical Society, 2006)The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state has received renewed interest recently due to the experimental indication of its presence in CeCoIn5, a quasi-two-dimensional (2D) d-wave superconductor. However direct ... -
Effect of unitary impurities on non-STM types of tunneling in high-T-c superconductors
(American Physical Society, 2000)Based on an extended Hubbard model, we present calculations of both the local (i.e., single-site) and spatially averaged differential tunneling conductance in d-wave superconductors containing nonmagnetic impurities in the ... -
Electron transport in normal-metal/superconductor junctions
(American Physical Society, 2000)On the basis of the Keldysh method of nonequilibrium systems, we develop a theory of electron tunneling in normal-metal-superconductor junctions. By using the tunneling Hamiltonian model (being appropriate for the tight-binding ... -
Local tunneling characteristics near a grain boundary of a d-wave superconductor as probed by a normal-metal or a low-T-c-superconductor STM tip
(American Physical Society, 2000)We study the local single-particle tunneling characteristics [as observed with scanning tunnel microscopy (STM)] for N-D and S-D tunneling, where D is a d-wave superconductor with a {100}{110} grain boundary. The tunneling ...
