Angle-resolved photoemission spectroscopy (ARPES) of magnetic topological materials & 2D systems

Angle-resolved photoemission spectroscopy (ARPES) has proven to be an essential tool to resolve the topological state of novel quantum materials. By allowing direct access to the electronic band structure, clear signatures of nontrivial topology like topological surface states or Weyl points can be detected. My goal is to combine lab-based (He I, laser) & synchrotron-based (VUV, soft-X-ray, spin-resolved, CDAD…) ARPES to resolve the topology of novel quantum materials.

So far, my research focus has been on studying magnetic topological materials (MnBi2Te4, MnSb2Te4), and we have plenty of ideas for studying 2D systems. Additionally, as an affiliated member of the QuMat program, I am thrilled to join forces with QuMat PhD Crystal Knekna in discussing and performing lab-based & synchrotron-based ARPES experiments on exciting new quantum materials relevant for the QuMat community!

At the time of writing (Dec 2023) I am in the 3rd year of my PhD.
