Topological magnetic heterostructures under moire superpotential

Dirac fermions on the surface of topological insulator (TI) are spin-momentum locked and topologically protected, making them perspective for spintronics and quantum computing applications. Creating moiré superlattices could dramatically enrich the physics of TIs, analogously to the new phenomena observed in twisted graphene layers. This project is devoted to the study of moire-modulated electronic structure of MnBi2Te4, Bi2Se3 and Bi2Te3 with transition-metal dichalides trilayers on top. The main aim of the project is to unveil the low energy band structure near the Dirac cone replicas crossing points, study the minigaps opening, reveal the renormalization of the Dirac fermions and possible van Hove singularities. Our observations will provide a new way to correlated topological phases, that may result in topological superconductivity, high-Chern number phases and, finally, topologically-protected quantum computing.
