Microscopic Scattering Approach to In-Gap States: Cr Adatoms on Superconducting β-Bi2Pd

Joseph Sink, Hari Paudyal, Divya Jyoti +4

We develop a microscopic scattering formalism to describe Yu-Shiba-Rusinov (YSR) states due to a single Cr adatom on the Bi-terminated surface of $\beta -B{i}_{2}Pd$, by combining ab initio…
