Probing atoms by periodically modulated electron bunches
A. B. Voitkiv, E. Schneidmiller, T. Pfeifer
When passing through an undulator in a Free Electron Laser, dense bunches of relativistic electrons split into micro-bunches, attaining a periodic space-time structure. We show tha…

Phase-resolved imaging of coherent phonon-magnon coupling
Yannik Kunz, Florian Kraft, David Breitbach +6
We use a direct phase-resolved optical technique to study the coherence of spin waves (SWs) that are driven by surface acoustic waves (SAWs) via resonant magnetoelastic coupling. F…
