Joint work of ML4Q members Mussler, Schüffelgen, Grützmacher and Schäpers at Forschungszentrum Jülich was recently published in Nanomaterials. The publication reports on results obtained in a study of the properties of superconductivity induced into a topological material in terms of direct current, radio frequency irradiation and the effect of magnetic fields. The findings include the agreement between simulation and experiment which indicates that the in-situ nano fabrication is a promising platform for complex superconducting networks. Furthermore, the observation of a fractional Shapiro step supports that topological materials may add rich physics to the multi terminal dynamics.
