Spin dynamics of electronic excitations
Angle-Resolved Photoemission Spectroscopy (ARPES) is an experimental technique that allows direct probing of the electronic band structure of metallic and semiconducting materials.
We extend this method by incorporating both spin and time resolution: spin detection enables the investigation of magnetic and topological properties, as well as effects related to spin–orbit coupling in electronic states, while time resolution, enabled by ultrashort laser pulses, makes it possible to track and disentangle charge and spin dynamics on femtosecond and picosecond timescales.
This unique combination (STARPES) provides a comprehensive view of advanced electronic phenomena, particularly in materials of interest for spintronics applications.
