Inferring the parameters of a mixture model based on observed data is a classical problem in machine learning that has received much attention from computer scientists and statisticians alike. One of the first computational approaches to this problem was given by Dempster, Laird, and Rubin (1977) in the form of the popular EM algorithm. The goal of their algorithm was to find the parameters whi...

We study the effect of strong spin-orbit coupling (SOC) on bound states induced by impurities in superconductors. The presence of SOC breaks the SU(2)-spin symmetry and causes the superconducting order parameter to have generically both singlet (s-wave) and triplet (p-wave) components. We find that in the presence of SOC the spectrum of Yu-Shiba-Rusinov (YSR) states is qualitatively different i...
