Defect-induced displacement of topological surface state in quantum magnet MnBiTe
Felix Lüpke, Marek Kolmer, Hengxin Tan +6
The study shows that antisite defects in the magnetic topological material MnBi₂Te₄ push its topological surface state deeper into the crystal, reducing the surface gap, as demonst…

Fingerprinting superconductors by disentangling Andreev and quasiparticle currents across tunable tunnel junctions
Petro Maksymovych, Sang Yong Song, Benjamin Lawrie +2
Tunneling Andreev reflection (TAR) spectroscopy offers a powerful new approach to fingerprint superconducting pairing symmetry at the atomic scale. By leveraging the exponential se…
