University of Cologne Uncovers Spectroscopic Evidence of Topological Superconductivity in TI Josephson Junctions
Physicists at the University of Cologne have found direct spectroscopic evidence for topological superconductivity in topological insulator Josephson junctions. This research supports the Fu-Kane theoretical model and offers a way to achieve topological superconductivity and Majorana zero modes without relying on destructive magnetic fields. The study used tunneling spectroscopy to observe phase-controlled energy gap closing and reopening, a key signature of topological superconductivity.

Phase-dependent ABSs in a TI Josephson junction. Physicists at the University of Cologne’s Topological Matter Laboratory, in collaboration with theoretical researchers at RWTH Aachen University, have conducted tunneling spectroscopy on topological insulator Josephson junctions, revealing signatures of phase-controlled energy gap closing and reopening. Published in Science Advances under the title Tunneling spectroscopy of topological insulator…
