Understanding XANES spectra of two-temperature warm dense copper using ab initio simulation
N. Jourdain, V. Recoules, L. Lecherbourg +2
Using ab initio molecular-dynamics simulations combined with linear-response theory, we studied the x-ray absorption near-edge spectra (XANES) of a two-temperature dense copper pla…

Hard X-rays from laser-wakefield accelerators in density tailored plasmas
Michaela Kozlova, Igor Andriyash, Julien Gautier +10
Betatron x-ray sources from laser-plasma accelerators combine compactness, high peak brightness, femtosecond pulse duration and broadband spectrum. However, when produced with Tera…

Femtosecond X-ray absorption spectroscopy in warm dense matter
Benoît Mahieu, Noémie Jourdain, Kim Ta Phuoc +5
Exploring and understanding ultrafast processes at the atomic level is a scientific challenge. Femtosecond X-ray Absorption Spectroscopy (XAS) is an essential experimental probing…
