A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Simulations of Collisional Effects in an Inner-Shell Solid-Density Mg X-Ray Laser
Shenyuan Ren, Sam Vinko, Justin S. Wark
Inner-shell K x-ray lasers have been created by pumping gaseous, solid, and liquid targets with the intense x-ray output of free-electron-lasers (FELs). For gaseous targets lasi…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
Development of a new quantum trajectory molecular dynamics framework
Pontus Svensson, Thomas Campbell, Frank Graziani +6
An extension to the wave packet description of quantum plasmas is presented, where the wave packet can be elongated in arbitrary directions. A generalised Ewald summation is constr…
Correlation energy of the paramagnetic electron gas at the thermodynamic limit
Sam Azadi, N. D. Drummond, S. M. Vinko
The variational and diffusion quantum Monte Carlo methods are used to calculate the correlation energy of the paramagnetic three-dimensional homogeneous electron gas at intermediat…
Non-thermal evolution of dense plasmas driven by intense x-ray fields
Shenyuan Ren, Yuanfeng Shi, Quincy Y. van den Berg +6
The advent of x-ray free-electron lasers (XFELs) has enabled a range of new experimental investigations into the properties of matter driven to extreme conditions via intense x-ray…
