X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Distinct element-specific nanoscale magnetization dynamics following ultrafast laser excitation
Emma Bernard, Rahul Jangid, Nanna Zhou Hagström +13
Time-resolved ultrafast extreme ultraviolet (EUV) magnetic scattering is used to study laser-driven ultrafast magnetization dynamics of labyrinthine domains in a [Co/Ni/Pt] multila…
Resonant Self-Diffraction of Femtosecond Extreme Ultraviolet Pulses in Cobalt
Alexei A. Maznev, Wonseok Lee, Scott K. Cushing +14
Self-diffraction is a non-collinear four-wave mixing technique well-known in optics. We explore self-diffraction in the extreme ultraviolet (EUV) range, taking advantage of intense…
Robust scenario for the generation of non-equilibrium topological fluctuation states
Kathinka Gerlinger, Rein Liefferink, Michael Schneider +12
The recently discovered topological fluctuation state provides a fascinating new perspective on the ultrafast emergence of topology in condensed matter systems. However, rather lit…
High energy-resolution transient ghost absorption spectroscopy
Alok Kumar Tripathi, Yishai Klein, Edward Strizhevsky +10
We demonstrate the measurement of ultrafast dynamics using ghost spectroscopy and a pump-probe approach with an optical pump and a short-wavelength radiation probe. The ghost spect…
