Effect of a Magnetic Field on Tunneling Conductance in Normal Metal d-Wave Superconductor Interfaces
Through the analytic solutions of the Bogoliubov de Gennes (BdG) equations the effect of a static and homogeneous magnetic field applied parallel to the interface of an NIS (N: Normal metal, S: superconductor and I: Insulator) junction on the differential conductance is calculated. For a dxy symmetry we obtain zero bias conductance peak that can be split by a magnetic field. The shift of the ze...
متن کاملTunneling conductance in normal metal - triplet superconductor junction
We calculate the tunneling conductance spectra of a normal metal / insulator / triplet superconductor from the reflection amplitudes using the Blonder-Tinkham-Klapwijk (BTK) formula. For the triplet superconductor we assume one special p-wave order parameter having line nodes and two two dimensional f -wave order parameters with line nodes breaking the time-reversal symmetry. Also we examine no...

متن کاملMean-field theory of a quasi-one-dimensional superconductor in a high magnetic field
At high magnetic field, the semiclassical approximation which underlies the Ginzburg-Landau (GL) theory of the mixed state of type II superconductors breaks down. In a quasi-1D superconductor (weakly coupled chains system) with an open Fermi surface, a high magnetic field stabilizes a cascade of superconducting phases which ends in a strong reentrance of the superconducting phase. The supercond...
متن کاملSuperconductor-normal junction in a strong magnetic field: the double quantum Hall effect
The integer quantum Hall effect with a superconducting contact is analyzed. It is shown that the conductance plateaus occur at σxy = 2ne /h which is double the usual value. Non-Andreev scattering at the interface and flux penetration into the superconductor are shown to not affect the result. The effect should be observable in InAs quantum wells with Nb a contact. Typeset using REVTEX 1 This pa...
