Full Minimal Coupling All-Electron Real-Time TDDFT for X-Ray-Matter Interactions
Daniel Schacher, Tod A. Pascal, Craig P. Schwartz +1
Standard real-time time-dependent density functional theory (RT-TDDFT) couples light to matter through a spatially uniform (dipole) vector potential, an approximation that breaks d…
The Surface Sensitivity of X-ray Second Harmonic Generation as a Function of Energy
Daniel Schacher, Tod A. Pascal, Keith V. Lawler +1
The surface sensitivity and probe depth in the x-ray regime of diamond for second harmonic generation (SHG) was investigated both analytically and computationally with velocity gau…
Ultra-fast yttrium hydride chemistry at high pressures via non-equilibrium states induced by x-ray free electron laser
Emily Siska, G. Alexander Smith, Sergio Villa-Cortes +24
Controlling the formation and stoichiometric content of desired phases of materials has become a central interest for the study of a variety of fields, notably high temperature sup…
Post-aragonite phases of CaCO at lower mantle pressures
Dean Smith, Keith V. Lawler, Miguel Martinez-Canales +7
The stability, structure and properties of carbonate minerals at lower mantle conditions has significant impact on our understanding of the global carbon cycle and the composition…
