Quasiparticle poisoning and Josephson current fluctuations induced by Kondo impurities.
We introduce a toy model that allows us to study the physical properties of a spin impurity coupled to the electrons in the superconducting island. We show that, when the coupling of the spin is of the order of the superconducting gap Delta, two almost degenerate subgap states are formed. By computing the Berry phase that is associated with the superconducting phase rotations in this model, we ...
متن کاملQuasiparticle scattering interference in superconducting iron pnictides
Using both two orbital and five orbital models, we investigate the quasiparticle interference QPI patterns in the superconducting SC state of iron-based superconductors. We compare the results for nonmagnetic and magnetic impurities in sign-changed s-wave cos kx · cos ky and sign-unchanged cos kx · cos ky SC states. While the patterns strongly depend on the chosen band structure details, the se...
متن کاملQuasiparticle interference in mono- and bilayer graphene
Scanning tunneling microscopy (STM) is a powerful method to determine the atomic structure and the morphology of 2-dimensional materials, while scanning tunneling spectroscopy (STS) gives access to their local density of electronic states. However, this determination alone does not directly yield the dispersive band structure, and certainly does not give access to more advanced electronic prope...
متن کاملQuasiparticle interference in iron-based superconductors
We systematically calculate quasiparticle interference QPI signatures for the whole phase diagram of iron-based superconductors. Impurities inherent in the sample together with ordered phases lead to distinct features in the QPI images that are believed to be measured in spectroscopic imaging-scanning tunneling microscopy. In the spin-density wave phase the rotational symmetry of the electronic...
