A3: Atomic-scale visualization of magnetic-field-tuned states in topological structures

Hidenori Takagi, Dennis Huang

The goal of the project is to combine scanning tunneling microscopy at cryogenic temperatures with the full three-dimensional tunability of a vector magnet to control topological band structures and realize exotic spatially varying states and boundary modes. We will investigate how Dirac fermions, flat bands, surface states and edge states in kagome materials respond to a magnetic field. We will also investigate how a parallel magnetic field may induce inhomogeneous and/or topological superconductivity in transition metal dichalcogenides.
