Phase diagram of geometric d-wave superconductor Josephson junctions
A. Gumann, N. Schopohl
We show that a constriction-type Josephson junction realized by an epitactic thin film of a d-wave superconductor with an appropriate boundary geometry exhibits intrinsic phase dif…
Modification of Born impurity scattering near the surface of d-wave superconductors and influence of external magnetic field
A. Zare, A. Markowsky, T. Dahm +1
We study the influence of Born impurity scattering on the zero-energy Andreev bound states near the surface of a d-wave superconductor with and without an externally applied magnet…
Andreev bound states at a cuprate grain boundary junction: A lower bound for the upper critical field
M. Wagenknecht, D. Koelle, R. Kleiner +6
We investigate in-plane quasiparticle tunneling across thin film grain boundary junctions (GBJs) of the electron-doped cuprate LaCeCuO in magnetic fields up to $B…
Shadow on the wall cast by an Abrikosov vortex
S. Graser, C. Iniotakis, T. Dahm +1
At the surface of a d-wave superconductor, a zero-energy peak in the quasiparticle spectrum can be observed. This peak appears due to Andreev bound states and is maximal if the nod…
Fermi surface topology and the upper critical field in two-band superconductors - application to MgB2
T. Dahm, N. Schopohl
Recent measurements of the anisotropy of the upper critical field Bc2 on MgB2 single crystals have shown a puzzling strong temperature dependence. Here, we present a calculation of…
