First results from HHG-based angle-resolved photoemission setup!

Our time-resolved ARPES setup is now operational! The image below shows a Dirac cone in the electronic band structure of a topological metal, measured using high-order harmonic probe pulses. This project is led by Dr. Yangyang Liu, in a collaboration with UCF’s Laboratory for Advanced Spectroscopic Characterization of Quantum Materials, led by Prof. Madhab Neupane.

Heat map showing ARPES measurements with momentum on the x-axis and energy (eV) on the y-axis. The data create an X-shaped pattern in warm tones.
