Abstract

Ultrafast spectroscopic techniques have been crucial to gain fundamental insights into the topological properties of materials. We employed ultrafast time-resolved angle-resolved photoemission spectroscopy to probe and elucidate surface electronic structure and electron dynamics of Z2 topological insulators, Dirac-Weyl semimetals and exotic spin-orbit superconductors. In this talk, I plan to present a few recent examples including Weyl semimetal class TaIr(Te/Se)4; MoxW1−xTe2 materials and bulk-insulating topological insulator Bi2Te2Se where ultrafast techniques have been crucial to discover the full topological behavior.
