TL;DR: QMCPACK as mentioned in this paper is an open source quantum Monte Carlo package for ab initio electronic structure calculations that supports calculations of metallic and insulating solids, molecules, atoms, and some model Hamiltonians.
Journal ArticleDOI
Beyond Darcy's law: The role of phase topology and ganglion dynamics for two-fluid flow
TL;DR: The results suggest that the role of fluid connectivity cannot be ignored for multiphase flow and show that fluid topology can undergo substantial changes during flow at constant saturation, which is one of the underlying causes of hysteretic behavior.
Journal ArticleDOI
Phase-coherent, injection-seeded, table-top soft-X-ray lasers at 18.9 nm and 13.9 nm

TL;DR: In this paper, gain-saturated pulses were produced in dense laser-created plasmas by amplifying high-harmonic seed pulses in the 18.9-nm and 13.9nm transitions of nickel-like molybdenum and silver ions, respectively.

Journal ArticleDOI
Demonstration of high-repetition-rate tabletop soft-x-ray lasers with saturated output at wavelengths down to 13.9 nm and gain down to 10.9 nm
Yong Wang,Miguel A. Larotonda,B. M. Luther,David Alessi,Mark Berrill,V.N. Shlyaptsev,Jorge J. Rocca +6 more
TL;DR: In this article, the authors demonstrated the saturation of tabletop x-ray lasers at 5 Hz repetition rate with average power 1 W at wavelengths between 16.5 and 13.9 nm in the 4d 1 S 0 −4 p 1 P 1 transitions of Ni-like ions.
