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…

Signatures of Green's function zeros and their topology using impurity spectroscopy
Sayan Mitra, Fang Xie, Marek Kolmer +2
Topology without quasiparticles has emerged as a key framework for understanding Mott insulators, where Green's-function zeros encode nontrivial topological structure. Yet, experim…
