Breaking time-reversal and translational symmetry at edges of -wave superconductors: microscopic theory and comparison with quasiclassical theory
N. Wall Wennerdal, A. Ask, P. Holmvall +2
We report results of a microscopic calculation of a second-order phase transition into a state breaking time-reversal and translational invariance along pair-breaking edges of -…
Phase Crystals
P. Holmvall, M. Fogelström, T. Löfwander +1
Superconductivity owes its properties to the phase of the electron pair condensate that breaks the symmetry. In the most traditional ground state, the phase is uniform and r…
Spontaneous symmetry-breaking at surfaces of -wave superconductors: influence of geometry and surface ruggedness
P. Holmvall, A. Vorontsov, M. Fogelstrom +1
Surfaces of -wave superconductors may host a substantial density of zero-energy Andreev states. The zero-energy flat band appears due to a topological constraint, but comes with…
Spectrum of Andreev Bound States in a Molecule Embedded Inside a Microwave-Excited Superconducting Junction
Jonas Skoldberg, Tomas Lofwander, Vitaly S. Shumeiko +1
Non-dissipative Josephson current through nanoscale superconducting constrictions is carried by spectroscopically sharp energy states, so-called Andreev bound states. Although theo…
Excess current in superconducting SrRuO
F. Laube, G. Goll, M. Eschrig +2
We present results from point-contact measurements on SrRuO that show a linear dependence of the excess current as a function of temperature and applied magnetic fields ove…
