Exact two-component TDDFT with simple two-electron picture-change corrections: X-ray absorption spectra near L- and M-edges of four-component quality at two-component cost
Lukas Konecny, Stanislav Komorovsky, Jan Vicha +2
X-ray absorption spectroscopy (XAS) has gained popularity in recent years as it probes matter with high spatial and elemental sensitivity. However, the theoretical modelling of XAS…
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
Anne-Lise Viotti, Chen Li, Gunnar Arisholm +4
Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers ar…
Multi-gigawatt peak power post-compression in a bulk multi-pass cell at high repetition rate
Ann-Kathrin Raab, Marcus Seidel, Chen Guo +5
The output of a 200 kHz, 34 W, 300 fs Yb amplifier is compressed to 31 fs with > 88 % efficiency to reach a peak power of 2.5 GW, which to date is a record for a single-stage bulk…
Exact 3D scattering solutions for spherical symmetric scatterers
Jon Vegard Venås, Trond Jenserud
In this paper, exact solutions to the problem of acoustic scattering by elastic spherical symmetric scatterers are developed. The scatterer may consist of an arbitrary number of fl…
Isogeometric Analysis of Acoustic Scattering using Infinite Elements
Jon Vegard Venås, Trond Kvamsdal, Trond Jenserud
Isogeometric analysis (IGA) has proven to be an improvement on the classical finite element method (FEM) in several fields, including structural mechanics and fluid dynamics. In th…
Generalization and stabilization of exact scattering solutions for spherical symmetric scatterers
Jon Vegard Venås, Trond Jenserud
In a previous work the authors described a fast high-fidelity computer model for acoustic scattering from multi-layered elastic spheres. This work is now extended with a scaling st…
