Phase transitions of eutectic high entropy alloy AlCoCrFeNi2.1 under shock compression
Sophie E. Parsons, Kento Katagiri, Hangman Chen +31
High entropy alloys (HEAs) are a new class of metals that exhibit unique mechanical performance. Among HEAs, additively manufactured eutectic high entropy alloys (AM-EHEAs) have re…
A simple method to find temporal overlap between THz and X-ray pulses using X-ray-induced carrier dynamics in semiconductors
Yuya Kubota, Takeshi Suzuki, Shigeki Owada +5
X-ray-induced carrier dynamics in silicon and gallium arsenide were investigated through intensity variations of transmitted terahertz (THz) pulses in the pico to microsecond time…
Comment on "Comments regarding "Transonic dislocation propagation in diamond" by Katagiri, et al. (Science 382, 69-72, 2023)" by Hawreliak, et al. (arXiv:2401.04213)
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
In their comment (1), Hawreliak et al. claims that our observation of stacking fault formation and transonic dislocation propagation in diamond (2) is not valid as they interpret t…
(Sub-)picosecond surface correlations of femtosecond laser excited Al-coated multilayers observed by grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Toshinori Yabuuchi +22
Femtosecond high-intensity laser pulses at intensities surpassing can generate a diverse range of functional surface nanostructures. Achieving prec…
Disentangling the Evolution of Electrons and Holes in photoexcited ZnO nanoparticles
Christopher J. Milne, Natalia Nagornova, Thomas Pope +27
The evolution of charge carriers in photoexcited room temperature ZnO nanoparticles in solution is investigated using ultrafast ultraviolet photoluminescence spectroscopy, ultrafas…
Pushing the limits of flow strength in diamond
Anirudh Hari, Kento Katagiri, Wanghui Li +34
Extreme pressures and temperatures create conditions that allow even hard and brittle materials to deform plastically. Despite extensive research, the upper limits of flow strength…
Photoelectron Angular Distributions for Two-photon Ionization of Helium by Ultrashort Extreme Ultraviolet Free Electron Laser Pulses
R. Ma, K. Motomura, K. L. Ishikawa +19
Phase-shift differences and amplitude ratios of the outgoing and continuum wave packets generated by two-photon ionization of helium atoms are determined from the photoelec…
