Awesome news everyone! Our preprint Theory of superconducting proximity effect in hole-based hybrid semiconductor-superconductor devices just got on the arxiv!!

Hybrid superconductor-semiconductor devices are promising on several fronts: quantum computation, topological physics, quantum engineering, you name it. Until the last couple of years, most works in these kind of devices were done in magnetically-noisy materials, limiting their potential. Recently, people has started to work on hole-based hybrid devices in Ge but the theory on them is quite limited so far. In this work we evaluate in an agnostic way the different forms in which superconducting correlations can translate into Ge hole spins, finding out very interesting physics: both singlet and triplet pairing terms are usual to be found, with strong magnetic field anisotropies. An f-type superconductivity is found as one of the most dominant terms in current experiments, showing an cubic-in-momentum dependence due to the cubic Rashba. Our work opens many doors, which we will be happy to explore in the near future.
