Welcome to our research group

Ultrafast Phenomena in Solids and at Interfaces

In the focus of our research are microscopic interaction mechanisms of charge, vibration, and magnetic degrees of freedom in condensed matter. We aim at an understanding of energy transfer between these subsystems and energy transport along spatial coordinates and focus on low dimensions and nanostructures.

Best paper award for Dr. Manuel Ligges et al. at Cenide anniversary celebration

Together with Dr. Tim Frigge, Dr. Boris Krenzer (both AG Horn-von Hoegen) and Andreas Lücke (Univ. Paderborn), Dr. Manuel Ligges received the best paper award of CENIDE for the outstanding quality of their publication "Optically excited structural transition in atomic wires on surfaces at the quantum limit" (Nature 544, 207 (2017)). The work was carried out in the framework of the Research Group FOR1700 and the Collaborative Research Center Sfb1242.

Poster award for Ljupka Stojechevska-Malbasic at ICFSI 16 

Dr. Stojchevska-Malbasic received the poster award for her presentation "Study of the photoinduced hidden state in 1T-TaS_2 single crystals doped with selenium by means of time-resolved photoemission spectroscopy". This work was carried out as a part of her Humboldt Research Fellowship.
