Martin Weinelt

Prof. Martin Weinelt is a Professor in the Department of Physics at Free University Berlin, where he leads the AG Weinelt research group focused on Ultrafast Surface Dynamics. His office is located at Arnimallee 14, Room 0.4.15, 14195 Berlin, in the Physics Department building in Dahlem.

His research interests include:

• Ultrafast Surface Dynamics
• Femtosecond Laser Pulse Interactions with Materials
• Electron Dynamics at Ferromagnetic Metal and Semiconductor Surfaces
• Coupling of Electronic Excitations to Nuclear Motion
• Vibrations, Molecular Switching and Phase Transitions
• Spin Transport in Topological Materials

Prof. Weinelt's research group investigates the geometrical and electronic structure of solids, thin films, and surfaces and their response to excitation by femtosecond laser pulses. The research spans from single electron dynamics to collective electronic responses to intense laser excitation, with particular focus on topological materials like Sb2Te2S. The group employs advanced experimental techniques including time-resolved photoelectron spectroscopy and utilizes facilities such as European XFEL.

Prof. Weinelt has supervised numerous students throughout his career, with former students completing research on topics including magnetization dynamics in lanthanide metals, spin transport, and topological surface states. Current group members include postdocs, PhD students, and Master's students working on various aspects of ultrafast surface science.

The AG Weinelt group is part of the Physics Department at Free University Berlin, located in Dahlem, southwest of Berlin. The department is well-connected to Berlin's public transport system, accessible by subway U3 to 'Dahlem-Dorf' station.
