THz Control of Exchange Mode in a Ferrimagnetic Cavity
Chris Reinhoffer, Ilya Razdolski, Philipp Stein +4
The interaction of terahertz (THz) radiation with high-frequency spin resonances in complex magnetic materials is central for modern ultrafast magnonics. Here we demonstrate strong…

Ultrafast Optical Control of Exciton Diffusion in WSe/Graphene Heterostructures Revealed by Heterodyne Transient Grating Spectroscopy
Lukas Rieland, Julian Wagner, Robin Bernhardt +8
Using heterodyne transient grating spectroscopy, we observe a significant enhancement of exciton diffusion within a monolayer WSe stacked on top of graphene. We further demonst…
