Shock-driven amorphization and melt in FeO
Céline Crépisson, Alexis Amouretti, Marion Harmand +28
We present measurements on FeO amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a d…
(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…
The importance of temperature-dependent collision frequency in PIC simulation on nanometric density evolution of highly-collisional strongly-coupled dense plasmas
Mohammadreza Banjafar, Lisa Randolph, Lingen Huang +17
Particle-in-Cell (PIC) method is a powerful plasma simulation tool for investigating high-intensity femtosecond laser-matter interaction. However, its simulation capability at high…
Transonic Dislocation Propagation in Diamond
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
The motion of line defects (dislocations) has been studied for over 60 years but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations pre…
Direct imaging of shock wave splitting in diamond at Mbar pressures
S. S. Makarov, S. A. Dyachkov, T. A. Pikuz +19
The propagation of a shock wave in solids can stress them to ultra-high pressures of millions of atmospheres. Understanding the behavior of matter at these extreme pressures is ess…
Nanoscale subsurface dynamics of solids upon high-intensity laser irradiation observed by femtosecond grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Thomas R. Preston +28
Observing ultrafast laser-induced structural changes in nanoscale systems is essential for understanding the dynamics of intense light-matter interactions. For laser intensities on…
Using Diffuse Scattering to Observe X-Ray-Driven Nonthermal Melting
N. J. Hartley, J. Grenzer, L. Huang +20
We present results from the SPring-8 Angstrom Compact free electron LAser (SACLA) XFEL facility, using a high intensity (W/cm) X-ray pump X-ray probe scheme to…
