Strong surface contribution to the Nonlinear Meissner Effect
A. Zare, T. Dahm, N. Schopohl
We demonstrate that in a d-wave superconductor the bulk nonlinear Meissner effect is dominated by a surface effect due to Andreev bound states at low temperatures. The contribution…
Geometric pi Josephson junction: Current-phase relations and critical current
A. Gumann, C. Iniotakis, N. Schopohl
Josephson junctions with an intrinsic phase shift of pi, so-called pi Josephson junctions, can be realized by a weak link of a d-wave superconductor with an appropriate boundary ge…
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…
