TL;DR: In this article, the authors report the achievement of fusion fuel gains exceeding unity on the US National Ignition Facility using a high-foot implosion method, which is a manipulation of the laser pulse shape in a way that reduces instability in the implosion.

TL;DR: In this paper, a low-Z capsule filled with deuterium-tritium (DT) fuel via laser indirect-drive inertial confinement fusion and demonstrate fusion ignition and propagating thermonuclear burn with a net energy gain of ∼5-10 (fusion yield/input laser energy).

TL;DR: In this article, an X-ray laser was used to observe the transition from plasmas and condensed matter to warm dense matter (WDM) in planetary interiors, and the transition to WDM was observed by using a WDM detector.

TL;DR: The comparison with radiation-hydrodynamic modeling indicates that low mode asymmetries and increased ablator surface perturbations may be responsible for the current performance of deuterium-tritium inertial confinement fusion implosion experiments.
