Megabar Shocks on a Benchtop
Yun Kai, Min Kim, Senpeng Lin +9
Techniques to generate megabar (100 GPa) pressure are critical for the study of materials under extreme conditions. However, kJ-class lasers are typically needed to generate such e…
Probing the wave-vector gap in nanoscale magnonics
Ondřej Wojewoda, Samer Kurdi, Toeno van der Sar +3
Short-wavelength spin waves are central to miniaturizing magnonic devices and to studying exchange-dominated magnetization dynamics. Yet the wave-vector range between roughly 30 an…
Phonon-dominated energy transport in purely metallic heterostructures
M. Herzog, A. von Reppert, J. -E. Pudell +5
We use ultrafast x-ray diffraction to quantify the transport of energy in laser-excited nanoscale Au/Ni bilayers. Electron transport and efficient electron-phonon coupling in Ni co…
Hard X-ray Transient Grating Spectroscopy on Bismuth Germanate
Jeremy R. Rouxel, Danny Fainozzi, Roman Mankowsky +44
Optical-domain Transient Grating (TG) spectroscopy is a versatile background-free four-wave-mixing technique used to probe vibrational, magnetic and electronic degrees of freedom i…
Direct Observation of Coherent Longitudinal and Shear Acoustic Phonons in TaAs Using Ultrafast X-ray Diffraction
Min-Cheol Lee, N. Sirica, S. W. Teitelbaum +18
Using femtosecond time-resolved X-ray diffraction, we investigated optically excited coherent acoustic phonons in the Weyl semimetal TaAs. The low symmetry of the (112) surface pro…
Nanoscale transient magnetization gratings excited and probed by femtosecond extreme ultraviolet pulses
D. Ksenzov, A. A. Maznev, V. Unni +15
We utilize coherent femtosecond extreme ultraviolet (EUV) pulses derived from a free electron laser (FEL) to generate transient periodic magnetization patterns with periods as shor…
