SUMMARY:Yu-Shiba-Rusinov states in two-dimensional superconductors. - (Mateo Uldemolins-Nivela / Seminar / LPT). - 08/11/2022
DESCRIPTION:Mateo Uldemolins-Nivela (LPS\, Orsay) \n  \nSummary\nA magnetic impurity on a conventional superconductor is one of the most simple pair-breaking defects that induces in-gap Yu-Shiba-Rusinov (YSR) bound states\, whose intricate spatial structure crucially influences the possibilities of engineering collective impurity states (e.g.\, Shiba chains\, lattices…) and topological superconductivity.\nIn this talk\, I will first introduce the paradigmatic model used to describe a magnetic impurity on a two-dimensional superconductor and I will discuss the main aspects of the YSR physics. Secondly\, I will present our recent work on the quasiparticle effect of YSR states\, where we use a generalized saddle-point approximation to unveil a simple analytical relationship between the spatial structure of the YSR bound states and the momentum-space anisotropy of the Fermi surface\, namely the angular dependent Fermi velocity and curvature of the Fermi surface.\nI will show that our analytical approximation is quantitatively accurate against tight-binding calculations in lattice models and I will discuss its application to describe the anisotropy of YSR states observed in scanning tunneling spectroscopy experiments of magnetic impurities on NbSe2. \n\n
