Research Abstract |
I have theoretically studied and investigated in order to determine superconducting pairing symmetries of nanostructure systems in anisotropic superconductors. The internal phase of pair potentials in the tunneling and Josephson junctions cause the formation of the Andreev resonant bound states, where the quasiparticles feel a sign change of the pair potential. We have suggested how to discriminate the pairing symmetries of a chiral p-wave superconductor from the vortex-core tunneling spectroscopy via odd-frequency pairing amplitudes.
