Biography

Hannes Kempf is a postdoc specializing in ultrafast spectroscopy and magneto-optical effects. He earned his Ph.D. in physics from the University of Konstanz, Germany, where he focused on the technological development of laser systems and field-resolved detection schemes using electro-optical sampling. Currently, he is part of the Ultrafast Nanoscience group at Umeå University, led by Dr. Nicolò Maccaferri. His current research primarily targets solid-state physics, particularly investigating magneto-optical effects using ultrafast pump-probe techniques. His main project involves the manipulation of magnetic phenomena induced by twisted plasmons generated from ultrashort laser pulses. Hannes is a member of the Ultrafast Nanoscience research group and is involved in projects aimed at ultrafast control of magnetism in twisted plasmons.
